Bidirectional Interleaved CCM Totem Pole Bridgeless PFC
Reference Design Using C2000™ MCU
Description Features
This reference design illustrates a method to control • Interleaved, 3.3-kW, Single-Phase, Bidirectional
a bidirectional interleaved continuous conduction Bridgeless CCM Totem Pole PFC Stage
mode (CCM) totem pole (TTPL) bridgeless power • 100-kHz Pulse Width Modulation (PWM) Switching
factor correction (PFC) power stage using a C2000™ • Programmable Output Voltage, 380-V DC Output
microcontroller (MCU) and LMG3410R070. This Nominal
power topology is capable of bidirectional power • Less Than 2% Total Harmonic Distortion (THD)
flow (PFC and grid-tied inverter) and it uses Gallium • Greater Than 98% Peak Efficiency
