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 comprises two boost converters operating with 180° out of phase, based on 600 V MDmesh M6 power MOSFETs.
The downstream section comprises a DC-DC phase-shifted full-bridge converter based on MDmesh DM6 power MOSFETs and performing voltage step down using HF transformer, with a primary to secondary ratio chosen to maintain high enough efficiency and regulation over the entire operating range.
On the primary side, the transformer is supplied by the full-bridge converter and switching losses are reduced thanks to zero voltage switching (ZVS) operation.
On the secondary side synchronous rectification (SR) is used to ensure low conduction losses.
The output voltage waveform is rectified by STripFET power MOSFETs and then smoothed by the output filter.
