TIDM-02008
Bidirectional high density GaN CCM totem pole PFC using C2000™ MCU
TIDM-02008
Overview
This reference design is a 3.-kW bidirectional interleaved continuous conduction mode (CCM) totem-pole (TTPL) bridgeless power factor correction (PFC) power stage using a C2000™ real-time controller and LMG3410R070 gallium nitride (GaN) with integrated driver and protection. This power topology is capable of bidirectional power flow (PFC and grid-tied inverter) and it uses LMG341x GaN devices, which enables higher efficiency and reduction in size of the power supply. The design supports phase shedding and adaptive dead time for efficiency improvements, input cap compensation scheme for improved power factor at light loads, and non-linear voltage loop to reduce voltage spikes under transient in PFC mode. The hardware and software available with this reference design accelerates time to market.
Features
- PFC mode: AC input (90-230 Vrms), 50-60 Hz and 3.3-KW rated power at high line
- Grid-tied inverter mode: DC input (Up to 400 V) and 3.3-KW rated power at high line
- 98.75% peak efficiency and less than 2% total harmonic distortion (THD)
- In-built frequency response analyzer (SFRA) for verification and design of control loops
- Low zero crossing distortion
- High power density design enabled by both GaN and C2000 controller high frequency operation
