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 ... https://www.ealisboa.com/top-sale-AR-10-Vert-Monoband-Indep-10m-2-Ringo-quick-deal/
