Description
General part information
STEVAL-ISA172V2 Series
The STEVAL-ISA172V2 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 STM32F334 microcontroller for each section.
The interleaved PFC comprises two boost converters operating with 180° out of phase, based on 600 V MDmesh M2 Power MOSFETs. The downstream section comprises of a DC-DC phase-shifted full-bridge converter based on MDmesh DM2 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.
