Description

The STEVAL-ISA172V3 is a 2 kW fully digital switch mode AC-DC converter consisting of two power sections: a two-phase interleaved power factor corrector (PFC) and a DC-DC phase-shifted full-bridge converter, controlled by a STM32G474RE microcontroller for each section.The interleaved PFC...
