High‐resolution FPGA‐pulse width modulation applied to PFC 2 MHz converter using eGaN field effect transistor

Abstract

This study proposes an implementation based on a low-cost field-programmable gate array (FPGA) of a high-resolution pulse width modulation applied on a single-phase power factor correction (PFC) converter operating with 2 MHz switch frequency. The PFC was implemented using a half-bridge enhancement-mode Gallium Nitride (eGaN) field effect transistor with on-board gate drives (EPC9003 development board) and the MAX10 FPGA.
