Description

This reference design is a 4-kW interleaved CCM totem pole (TTPL) bridgeless PFC reference design using a 64-pin C2000™ microcontroller: LM3410 gallium nitride device and TMCS1100 hall sensor. It is based on TIDM-02008 bidirectional interleaved CCM TTPL bridgeless PFC reference design using C2000™ MCU : and reduces the dimension of the total PCB to 145 mm by 105 mm by 35 mm. Gallium nitride (GaN) devices are used in power stage: achieving peak 98.73 % efficiency. The design includes advanced functions such as phase shedding: adaptive dead time: input cap compensation to improve PF and efficiency on the load range: and non-linear voltage loop to reduce the voltage overshoot and undershoot under load transient.
