STMicroelectronics A2F12M12W2-F1 | Demoboard STDES-DABBIDIR
25 kW, dual active bridge bidirectional power converter for EV charging and battery energy storage systems
Overview
| Topology | LLC Resonant Converter |
| Input voltage | 800 V |
| Output 1 | 800 V |
| IC revision | 1.0 |
Description
The STDES-DABBIDIR provides a complete solution for a bidirectional DC-DC power converter.A dual active bridge topology based on an ACEPACK 2 SiC power module 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.
