Interleaved CCM Totem Pole Bridgeless PFC ReferenceDesign Using C2000™ MCU

Overview

TopologyPower Factor Correction
IC revisionC

Description

This reference design illustrates a method to controlan interleaved continuous conduction mode (CCM)totem pole (TTPL) bridgeless power factor correction(PFC) power stage using a C2000™ microcontroller(MCU) and LMG3410. This power topology usesGallium Nitride (GaN) devices, which enables higherefficiency and reduction in size of the power supply.The design supports phase shedding and adaptivedead time for efficiency improvements, input capcompensation scheme for improved power factor atlight loads, and non-linear voltage loop to reducevoltage spikes under transient. The hardware andsoftware available with this reference designaccelerates time to market.
