TIDM-02013 is a bidirectional onboard charger reference design. The design consists of an interleaved continuous conduction mode (CCM) totem-pole (TTPL) bridgeless power-factor correction (PFC) power stage followed by a CLLLC DCDC power stage all controlled using a single C2000™ real-time control microcontroller (MCU), while utilizing a TI gallium nitride (GaN) power module.
This power topology is capable of bidirectional power flow (PFC and grid-tied inverter) and uses GaN devices, which enables higher efficiency and reduction in size of the power supply. The hardware and software available with this reference design accelerates time to market.
Features
- PFC mode: AC input (90 VRMS to 264 VRMS), 50 Hz to 60 Hz and 7.4-kW-rated power at high line
- 96.5% peak total-system efficiency
- Power density of 3.8 kW/L
- In-built frequency response analyzer (SFRA) for verification and design of control loops
- Low zero crossing distortion as well as active synchronous rectification
