GaN-based 5kW two-phase totem-pole PFC reference design with zero current detection
PMP23475
概述
This reference design is a high-density and high-efficiency, 5kW power factor correction (PFC) converter implemented with TI high-performance Gallium Nitride (GaN) power switches. A peak system efficiency of 99.2% with an open-frame power density of 120W/in3 was measured. The power stage uses a two-phase totem pole PFC in a brand new zero current detection (ZCD) based control mechanism. The new control method operates with variable frequency and maintains zero voltage switching (ZVS) over all operating conditions. The control is implemented with a TMS320F280039C high-performance microcontroller and the LMG3527R030 GaN field effect transistor (FET) with integrated ZCD sensing. The operating frequency range of the converter is approximately between 100kHz and 800kHz.
