製品概要
概要
STSW-DABBIDIR provides a complete and sophisticated solution to control a dual active bridge (DAB) bidirectional DC-DC power converter, exploiting a mixed-signal digital platform optimized for digital power applications.
A complete software solution is provided to exploit several application advantages offered by the flexible DAB topology.
The provided firmware allows operating the DAB converter with extended soft switching thanks to the adaptive modulation techniques and enhanced voltage and load control at wide range.
The STM32G474RET3 high performance MCU allows maximizing the DAB topology advantages in DC-DC applications, such as EV DC fast charging, energy storage systems, and UPS applications.
Additional firmware features like input and output protections, and soft startup are provided.
