100W GaN FET development board for AirFuel wireless power standard

February 18, 2016 // By Graham Prophet
Rated at 100W, and claiming 92% efficiency, from Efficient Power Conversion (EPC) the EPC9065 eGaN FET development board targets the 6.78 MHz AirFuel wireless power standard

The board serves as the amplifier stage for AirFuel Alliance Class 4 and Class 5 wireless power transfer applications. This board is a Zero Voltage Switching (ZVS) differential-mode class-D amplifier development board configured at, but is not limited to, 6.78 MHz (Lowest ISM band). The EPC9065 includes all the critical components, including two screw-mounted heat sinks for increased power capability. It can be connected into an existing system to speed end-product time to market.

This development board features the EPC2007C and the EPC8010, which are 100-V rated enhancement-mode gallium nitride FETs. The EPC2007C is used in the class-D amplifier while the EPC8010 is used as a synchronous bootstrap FET. The amplifier can be set to operate in either differential or single-ended mode and includes the gate drivers, a 6.78 MHz oscillator, and a separate heat sink for each Class-D section.

Quick Start Guides, containing set-up procedures, circuit diagram, bill of material and Gerber files for the boards are provided on-line at http://epc-co.com/epc/Products/DemoBoards.aspx

The EPC9065 is priced at $414.00 and is available from Digi-Key .
