EPC9507 is the amplifier (source) board for a ZVS Class-D wireless power transfer system. The EPC9507 is a high efficiency, Zero Voltage Switching (ZVS), Class-D Wireless Power amplifier demonstration board operating at 6.78 MHz (Lowest ISM band). The EPC9507 features the EPC2007C and EPC2038 enhancement mode field effect transistors (FET) in an optional half-bridge topology (single ended configuration) or default full-bridge topology (differential configuration), and includes the gate driver/s and oscillator that ensures operation of the system at 6.78 MHz. This revision of the wireless demonstration amplifier includes a synchronous bootstrap FET supply for the upper FETs of the ZVS class D amplifier that eliminates the reverse recovery losses of the gate driver’s internal bootstrap diode that dissipates energy in the upper FET. This circuit has been implemented using the new EPC2038 eGaN FET specifically designed for this function. The EPC9507 amplifier board can be purchased as part of the EPC9112 wireless power system demonstration kit or as a stand-alone board.
