Demonstration System EPC9506 Quick Start Guide ZVS Class-D Wireless Power Amplifier Demo Board using EPC2014
QUICK START GUIDE
Demonstration System EPC9506
DESCRIPTION The EPC9506 is a high efficiency, Zero Voltage Switching (ZVS), Class-D Wireless Power amplifier demonstration board operating at 6.78 MHz (Lowest ISM band). The purpose of this demonstration system is to simplify the evaluation process of wireless power technology using eGaN® FETs by including all the critical components on a single board that can be easily connected into an existing system. The amplifier board features the EPC2014 (40 V rated - EPC9506) enhancement mode field effect transistor (FET) in an optional half-bridge topology (single ended configuration) or default fullbridge topology (differential configuration), and includes the gate driver/s and oscillator that ensures operation of the system at 6.78 MHz. The amplifer board can also be operated using an external oscillator. The amplifier board is equipped with a pre-regulator that limits the current of the supply to the amplifier. As the amplifier draws more current, which can be due to the absence of a device coil, the pre-regulator will reduce the voltage being supplied to the amplifier that will ensure a safe operating point. The pre-regulator also monitors the temperature of the main amplifier FETs and will reduce current if the temperature exceeds 85°C. The pre-regulator can be bypassed to allow testing with custom control hardware. The board further allows easy access to critical measurement nodes that allow accurate power measurement instrumentation hookup. A simplified diagram of the amplifier board is given in Figure 1.

QUICK START GUIDE
DESCRIPTION The Amplifier Board (EPC9506) Figure 1 shows a diagram of the EPC9506 ZVS class D amplifier with preregulator. The pre-regulator is set to a specified DC output current limit (up to 1.5 A) by adjusting P49 and operates from 8 V through 36 V input. The output voltage of the pre-regulator is limited to approximately 2 V below the input voltage. The pre-regulator can be bypassed by moving the jumper (JP60) over from the right 2 pins to the left 2 pins. To measure the current the amplifier is drawing, an ammeter can be inserted in place of the jumper (JP60) in the location based on the operating mode (pre-regulator or bypass). The amplifier comes with its own oscillator that is pre-programmed to 6.78 MHz ± 678 Hz. It can be disabled by placing a jumper into J70 or can be externally shutdown using an externally controlled open collector / drain transistor on the terminals of J70 (note which is the ground connection). The switch needs to be capable of sinking at least 25 mA. An external oscillator can be used instead of the internal oscillator when connected to J71 (note which is the ground connection) and the jumper (JP70) is moved from the right 2 pins to the left 2 pins. The pre-regulator can also be disabled in the same manner as the oscillator using J51. The pre-regulator can be bypassed, to increase the operating voltage (with no current or thermal protection) to the amplifier or to use an external regulator, by moving the jumper JP60 from the right 2 pins to the left 2 pins. Jumper JP60 can also be used to connect an ammeter to measure the current drawn by the amplifier (make sure the ammeter connects to the pins that correspond to the mode of operation either bypass or pre-regulator). Single Ended Operation The amplifier can be configured for single ended operation where only devices Q1 and Q2 are used. In this mode only LZVS1 and CZVS are used to establish ZVS operation. If Q11 and Q12 are populated, then the following changes need to be made to the board: 1) Remove R76 and R77 2) Short out C46 and C47 3) Short the connection of JMP1 (back side of the board)
Demonstration System EPC9506 1. Remove the jumper in JP60 and insert it into J51 to place the EPC9506 amplifier in bypass mode. With power off connect the main input power supply (+) bus to the center pin of JP60 (pin 2) and the ground of the main power to the ground (-) connection of J50 -VIN. 2. With power off, connect the control input power supply bus to +VDD (J90). Note the polarity of the supply connector. 3. Connect a LOW capacitance oscilloscope probe to the probe-hole J2 and lean against the ground post as shown in Figure 2. 4. Turn on the control supply – make sure the supply is between 7 V and 12 V range (7.5 V is recommended). 5. Turn on the main supply voltage to the required predominant operating value (such as 24 V but NEVER exceed the absolute maximum voltage of 32 V). 6. While observing the oscilloscope adjust P74 for the rising edge of the waveform so achieve the green waveform of figure 4. Repeat for the falling edge of the waveform by adjusting P75. 7. Check that the setting remains optimal with a source coil attached. In this case it is important that the source coil is TUNED to resonance WITH an applicable load. Theoretically the settings should remain unchanged. Adjust if necessary. 8. Replace the potentiometers with fixed value resistors. Configure the EPC9506 amplifier back to normal operation by removing the power connections to J50 and JP60, removing the jumper in J51 and inserting it back into JP60 (right 2 pins 2 & 3). Differential Operation The amplifier can be configured for differential operation where all the devices are used; Q1, Q2, Q11 and Q12. In this mode either LZVS1, LZVS11 and CZVS or LZVS12 only is used to establish ZVS operation. Determining Component Values for LZVS The ZVS tank circuit is not operated at resonance, and only provides the necessary negative device current for self-commutation of the output voltage at turn off. The capacitance CZVS is chosen to have a very small ripple voltage component and is typically around 1 µF. The amplifier supply voltage, switch-node transition time will determine the value of inductance for LZVSx which needs to be sufficient to maintain ZVS operation over the DC device load resistance range and coupling between the device and source coil range and can be calculated using the following equation: LZVS =
4) Remove LZVS12 (if populated)
8 ∙ fsw∙ COSSQ
5) Add LZVS1 (270 nH) 6) Check that CZVS1 is populated, if not then install. 7) R74 and R75 may need to be adjusted for the new operating condition to achieve maximum efficiency (see section on ZVS timing adjustment). ZVS Timing Adjustment Setting the correct time to establish ZVS transitions is critical to achieving high efficiency with the EPC9506 amplifier. This can be done by selecting the values for R74 and R75 respectively. This procedure is best performed using potentiometer P74 and P75 installed that is used to determine the fixed resistor values. The procedure is the same for both single ended and differential mode of operation. The timing MUST initially be set WITHOUT the source coil connected to the amplifier. The timing diagrams are given in Figure 4 and should be referenced when following this procedure. Only perform these steps if changes have been made to the board as it is shipped preset. The steps are:
∆tvt
(1)
Where: Δtvt = Voltage transition time [s] fsw = Operating frequency [Hz] COSSQ = Charge equivalent device output capacitance [F]. Note that the amplifier supply voltage VAMP is absent from the equation as it is accounted for by the voltage transition time. The charge equivalent capacitance can be determined using the following equation: COSSQ =
1 VAMP
∙
∫
VAMP
COSS (v) ∙ dv
(2)
0
To add additional immunity margin for shifts in coil impedance, the value of LZVS can be decreased to increase the current at turn off of the devices (which will increase device losses). Typical voltage transition times range from 2 ns through 12 ns. For the differential case the voltage and charge (COSSQ) are doubled.

QUICK START GUIDE
Demonstration System EPC9506
QUICK START PROCEDURE The EPC9506 amplifier board is easy to set up and evaluate the performance of the eGaN FET in a wireless power transfer application.
3. With power off, connect the control input power supply bus to +VDD (J90). Note the polarity of the supply connector.
The EPC9506 can be operated using any one of two alternative methods:
4. Select and connect an applicable load resistance to the device board.
a. Using the pre-regulator
5. Make sure all instrumentation is connected to the system.
b. Bypassing the pre-regulator
6. Turn on the control supply – make sure the supply is between 7 V and 12 V range (7.5 V is recommended).
a. Operation using the pre-regulator The pre-regulator is used to supply power to the amplifier in this mode and will limit the DC current to the amplifier based on the setting. The pre-regulator also monitors the temperature of the amplifier and will limit the current in the event the temperature exceeds 85°C.
7. Turn on the main supply voltage to the required value (it is recommended to start at 2 V and do not exceed the absolute maximum voltage of 32 V).
1. Make sure the entire system is fully assembled prior to making electrical connections and make sure jumper (JP60 is set to pre-regulator – right 2 pins).
8. Once operation has been confirmed, adjust the main supply voltage within the operating range and observe the output voltage, efficiency and other parameters on both the amplifier and device boards. See Pre-Cautions when operating in the bypass mode
2. With power off, connect the main input power supply bus to +VIN (J50). Note the polarity of the supply connector.
9. For shutdown, please follow steps in the reverse order. Start by reducing the main supply voltage to 0 V followed by steps 6 through 2.
3. With power off, connect the control input power supply bus to +VDD (J90). Note the polarity of the supply connector.
NOTE. When measuring the high frequency content switch-node (Source Coil Voltage), care must be taken to avoid long ground leads. An oscilloscope probe connection (preferred method) has been built into the board to simplify the measurement of the Source Coil Voltage (J2 and J3 as shown in Figure 3).
4. Select and connect an applicable load resistance to the device board. 5. Make sure all instrumentation is connected to the system.
THERMAL CONSIDERATIONS
6. Turn on the control supply – make sure the supply is between 7 V and 12 V (7.5 V is recommended).
The EPC9506 demonstration system showcases the EPC2014 eGaN FET in a wireless energy transfer application. Although the electrical performance surpasses that of traditional silicon devices, their relatively smaller size does magnify the thermal management requirements. The operator must observe the temperature of the gate driver and eGaN FETs to ensure that both are operating within the thermal limits as per the datasheets.
7. Turn on the main supply voltage to the required value (it is recommended to start at 8 V and do not exceed the absolute maximum voltage of 32 V ). 8. Once operation has been confirmed, adjust the main supply voltage within the operating range and observe the output voltage, efficiency and other parameters on both the amplifier and device boards. 9. For shutdown, please follow steps in the reverse order. Start by reducing the main supply voltage to 0 V followed by steps 6 through 2.
NOTE. The EPC9506 demonstration system has limited current and thermal protection only when operating off the Pre-Regulator. When bypassing the pre-regulator there is no current or thermal protection on board and care must be exercised not to over-current or overtemperature the devices. Wide coil coupling and load range variations can lead to increased losses in the devices.
b. Operation bypassing the pre-regulator
Pre-Cautions
In this mode, the pre-regulator is bypassed and the main power is connected directly to the amplifier . This allows the amplifier to be operated using an external regulator.
The EPC9506 demonstration system has no controller or enhanced
In this mode there is no current or thermal protection for the eGaN FETs.
1. Please contact EPC at
[email protected] should the tuning of the coil be required to change to suit specific conditions so that it can be correctly adjusted for use with the ZVS Class-D amplifier.
1. Make sure the entire system is fully assembled prior to making electrical connections and remove the jumper JP60. Never connect the main power positive (+) to J50 when operating in bypass mode. 2. With power off, connect the main input power supply ground to the ground terminal of J50 (-) and the positive (+) to the center pin of JP60.

protections systems and therefore should be operated with caution. Some specific precautions are:
2. There is no heat-sink on the devices and during experimental evaluation it is possible present conditions to the amplifier that may cause the devices to overheat. Always check operating conditions and monitor the temperature of the EPC devices using an IR camera.
