Key Benefits
Description
The STDES-30KWVRECT reference design introduces a complete digital power solution for high-power three-phase 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 STPSC40H12C.
It features a fully digital control with the STM32G474RE 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.
