11kW three-phase bidirectional onboard charger and low-voltage DC-DC reference design with F29x MCU
TIDM-02021
概述
This reference design integrates an 11kW onboard charger (OBC) and a 2.5kW low-voltage (LV) DC- DC converter (LDC). The design uses a three-phase single-stage series resonant dual-active-bridge AC- DC converter topology. TI F29x MCUs and Type-5 enhanced pulse-width-modulator (ePWM) support the complex modulation of the three-phase AC-DC converter.
特性
- 11kW maximum power and 97.5% peak efficiency for OBC
- VAC(ph): 175–264V; Nominal 220V
- VHVDC: 450–850V (high-voltage (HV) battery voltage range)
- Three-phase single-stage series resonant dual active bridge (SS-SRDAB) enables ZVS and ZCS soft-switching operation
- 150kHz resonant frequency (80kHz–250kHz operating range) enables high power density
- Supports bidirectional power flow for G2V and V2L and V2G modes
- 2.5kW maximum power for LDC
- VLVDC: Nominal 14V
- Single MCU for OBC and LDC closed-loop control
- Type-5 ePWM simplifies the complex PWM modulation for three-phase single-stage converter
