Description
The EPC9111 Wireless power demonstration system is a high efficiency, A4WP compatible, Zero Voltage Switching (ZVS), Class-D Wireless Power transfer demonstration kit capable of delivering up to 35 W into a DC load while operating at 6.78 MHz (Lowest ISM band). It includes an amplifier board (EPC9506) with a pre-regulator that limits the output current and voltage and ensures proper operation of the amplifier regardless of coupling and load variations between the source and device. The purpose of this demonstration system is to simplify the evaluation process of the wireless power technology using eGaN® FETs. The EPC9111 wireless power system comprises three boards (shown in figure 1) namely:1) A Source Board (Transmitter or Power Amplifier) EPC9506 2) A Class 3 A4WP compatible Source Coil (Transmit Coil)3) A Category 3 A4WP compatible Device Coil with rectifier and DC smoothing capacitor.The amplifier board features the EPC2014C and EPC2038 enhancement mode field effect transistor (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 The amplifier board can also be operated using an external oscillator or by using the included ultra low power oscillator.This revision can operate in either Single ended or Differential mode by changing a jumper setting. This allows for high efficiency operation with load impedance ranges that allow for single ended operation.
