Product overview

Description

The STSW-VRECTFD provides a comprehensive three-phase, three-level AC-DC power conversion control on the STM32G474RET3 mixed-signal MCU, which is optimized for digital power applications. The firmware includes a sophisticated voltage-oriented control (VOC) algorithm to control AC-DC conversion.
A highly dynamic current control based on the current decoupling technique performs PFC.
