製品概要

概要

The STDES-VRECTFD reference design is a complete solution for high-power three-phase AC/DC rectifier applications based on the Vienna topology.

It features full digital control through the STM32G474RET3 MCU and provides both digital output voltage regulation and continuous conduction mode (CCM) current regulation for the maximum power quality related to total harmonic distortion (THD) and power factor (PF).
The high switching frequency of the SCTW35N65G2V SiC MOSFETs (70 kHz) and the multilevel structure allow a nearly 99% efficiency as well as the optimization of passive power components in terms of size and cost.
This high efficiency Vienna rectifier is designed for several end applications, such as electric vehicle (EV) and industrial battery chargers, and industrial equipment that requires a very high PF and a low THD.
The STDES-VRECTFD is a fully assembled kit developed for performance evaluation only, not available for sale.
