EPC9130 Regulated Converter

EPC's EPC9130 development board is a 500 kHz switching frequency, 48 V nominal input voltage, 60 A maximum output current, 5-phase intermediate bus converter (IBC). It contains an onboard microcontroller and gate drives, featuring the 100 V EPC2045 enhancement mode (eGaN®) field effect transistor (FET). This development board provides a regulated 12 V power supply for high-performance applications showcasing the superior performance of the EPC2045 eGaN FET.

The EPC9130 development board has five phases of two EPC2045 eGaN FETs in a half bridge configuration using a uPI semiconductor up1966A gate driver with supply and bypass capacitors. The PWM signals to the gate drivers are fed by an onboard dsPIC33 microcontroller from Microchip®. The output voltage is regulated to 12 V. The board contains all critical components and a layout for optimal switching performance. There are also various probe points to facilitate simple waveform measurement and efficiency calculation.
