Product overview
Description
The STSW-BCBIDIR provides a solution to control the double-stage STDES-BCBIDIR power converter exploiting a mixed-signal digital MCU optimized for digital power applications.
The STM32Cube development environment is fully integrated to extend and simplify the user approach.
The PFC firmware handles complete three-phase, two-level AC-DC, and DC-AC power conversion control based on the STM32G474RE. The firmware includes a sophisticated voltage-oriented control (VOC) algorithm to handle either the power factor in AC-DC conversion or the AC output power (active and reactive) in DC-AC conversion.
The DC-DC firmware allows to operate the converter with extended soft switching thanks to the adaptive modulation techniques and enhanced voltage and load control at a wide range.
Additional features to improve reliability and safety are provided, for example, input and output overvoltage and overcurrent protections, soft startup.
