Product overview
Description
The STDES-DABBIDIR provides a complete solution for a bidirectional DC-DC power converter.
A dual active bridge topology based on ACEPACK 2 SiC power modules is proposed.
The STM32G474RE MCU, enabling digital-intensive power control and optimized for mixed-signal applications, is used.
Thanks to the latest generation SiC power module and high-frequency operation (100 kHz), high performance and design optimization are reached.
Soft switching DAB behavior is managed by adaptive modulation techniques, according to the load/voltage variation.
Bidirectional mode operation supports V2G and V2L implementations as well as UPS and battery energy storage applications.
