Key Document
Description
CLLLC resonant DAB with bidirectional power flow capability and soft switching characteristics is an ideal candidate for Hybrid Electric Vehicle/Electric Vehicle (HEV/EV) on-board chargers and energy storage applications. This design illustrates control of this power topology using a C2000™ MCU in closed voltage and closed current-loop mode. The hardware and software available with this design help accelerate
your time to market.
Features
- Vprim: 380–600 V DC; Vsec: 280–450 V DC; Power Max: 6.6 kW; 98% peak efficiency
- CLLLC resonant tank with 500-kHz nominal PWM switching (300 kHz–700 kHz range) enables higher power density
- Soft switching with zero voltage switching (ZVS) on the primary; zero current switching (ZCS) and ZVS on the secondary enable higher efficiency
- Active synchronous rectification scheme implementation using on chip resources on C2000 MCU and Rogowski coil sensor implementation using Rogowski coil sensor enables higher efficiency
- Software frequency response analyzer (SFRA) and compensation designer for ease of tuning of control loops
- Software support for TMS320F28004x device with the control law accelerator (CLA), which enables integrated OBC design with AC-DC and DC-DC controlled using a single C2000 MCU
