Description

The EPC9509 is a high efficiency, Zero Voltage Switching (ZVS), class-Dwireless power amplifier demonstration board that operates at 6.78 MHz(Lowest ISM band). The purpose of this demonstration system is to simplifythe evaluation process of wireless power amplifier technology usingeGaN® FETs by including all the critical components on a single boardthat can be easily connected into an existing system.The amplifier board features the enhancement-mode, half-bridge fieldeffect transistor (FET), the 60 V rated EPC2108 eGaN FET with integratedsynchronous bootstrap FET. The amplifier can be set to operate in eitherdifferential mode or single-ended mode and includes the gate driver/s,oscillator, and feedback controller for the pre-regulator that ensuresoperation for wireless power control based on the A4WP standard. Thisallows for testing compliant to the A4WP class 3 standard over a loadrange as high as ±50j Ω. The pre-regulator features the 100 V rated 65 mΩEPC2036 as the main switching device for a SEPIC converter.For more information on the EPC2108 eGaN FETs please refer to the datasheetavailable from EPC at www.epc-co.com. The datasheet should beread in conjunction with this quick start guide.
