Texas Instruments UCC21710 | Demoboard TIDA-010054
Bi-directional, dual active bridge reference design for level 3 electric vehicle charging stations
Overview
| Topology | Half-Bridge Converter symmetrical isolated |
| Input voltage | 700-800 V |
| Output 1 | 500 V / 26 A |
| IC revision | April 2024 |
Description
This reference design provides an overview on the implementation of a single-phase dual active bridge (DAB) DC/DC converter. DAB topology offers advantages like soft-switching commutations, a decreased number of devices and high efficiency. The design is beneficial where power density, cost, weight, galvanic isolation, high voltage conversion ratio and reliability are critical factors, making it ideal for EV charging stations and energy storage applications. Modularity and symmetrical structure in DAB allow for stacking converters to achieve high power throughput and facilitate a bidirectional mode of operation to support battery charging and discharging applications.
Features
Smart Gate driver UCC21710 providing integrated protection for SiC MOSFETs
TMS320F280039 controller for implementation of digital controlPrimary voltage of 700V to 800V DC, secondary voltage of 350V to 500V DC (SPS) 250V to 500V (EPS)Achieves peak efficiency of 98.7% and full load efficiency of 98%PWM switching frequency of 100kHz and reduced transformer size enabled by planar magneticsMaximum power output of 10kW
Typical applications
- Hybrid, electric and powertrain systems
- Power conversion system (PCS)
- DC fast charging power module
- DC fast charging station
