Efficient Power Conversion (EPC) has introduced the EPC9065, a development board that can serve as the amplifier stage for AirFuelTM 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). This is the curently the highest power and highest efficiency soltion for the AirFuel wireless power standard, using eGaN® FETs.
The EPC9065 includes all the critical components, including two screw-mounted heat sinks for increased power capability. It can be easily 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 here on their website.
Price and Availability
The EPC9065 is priced at $414.00 each and are available for immediate delivery from Digi-Key.
