EPC9111(#2): 35W, Class 3, Rezence (A4WP) Compatible

The EPC9111 Wireless power demonstration system is a high efficiency, A4WP compatible, Zero Voltage Switching (ZVS), Voltage Mode 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. GaN

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 compliant Source Coil (Transmit Coil)
  

• 3) A Category 3 A4WP compliant Device Coil with rectifier and DC smoothing capacitor.
