High efficiency GaN CCM totem pole bridgeless Power Factor Correction (PFC) reference design
Description
Interleaved Continuous Conduction Mode (CCM) Totem Pole (TTPL) Bridgeless Power Factor Correction (PFC) is an attractive power topology with use of high band-gap GaN devices: because of high efficiency and reduced size of the power supply. This design illustrates a method to control this power stage using C2000™ MCUs and the LMG3410 GaN FET module. Adaptive dead-time & phase shedding methods are implemented for improved efficiency. The Non- Linear Voltage Compensator is designed to reduce overshoot and undershoot during transients. A software phase locked loop(SPLL) based scheme is chosen to drive the totem pole bridge accurately. The hardware and software available with this design helps accelerate your time to market.
