Product overview
Description
The firmware provides comprehensive three-phase, three-level and two-level AC/DC and DC/AC power conversion control on the STM32G474 mixed-signal MCU optimized for Digital Power. The firmware includes a sophisticated voltage oriented control (VOC) algorithm to control either the Power Factor in AC/DC conversion or the AC output power (active and reactive) in DC/AC conversion.
