STMicroelectronics STM32G474RET3 | Demoboard STDES-30KWVRECT
Getting started with the STDES-30KWVRECT 30 kW Vienna PFC rectifier reference design
Overview
| Topology | Other Topology |
| IC revision | 1 |
Description
The STDES-30KWVRECT reference design introduces a complete digital power solution for high-power threephase active front end (AFE) rectifier applications based on the three-level Vienna topology. This platform achieves a peak efficiency of more than 98.5% by using the SCTWA90N65G2V-4 and the STPSC40H12CWL.It features a fully digital control with the STM32G474RET3 mixed-signal high-performance microcontroller, providing the full control of the PF, DC voltage, and soft startup procedure. The STDES-30KWVRECT achieves a low total harmonic distortion (less than 5% THD at full load) and a high power factor (higher than 0.99 at full load), providing a high-bandwidth continuous conduction mode (CCM) current regulation. The STDES-30KWVRECT is a fully assembled kit developed for performance evaluation only, not available for sale.
Features
