STEVAL-ISA172V1, 2kW Fully Digital AC-DC Power Supply (D-SMPS) Evaluation Board
STEVAL-ISA172V1, Evaluation Board 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 an STM32F334 microcontroller for each section. The interleaved PFC comprises two boost converters operating 180 out of phase, based on 600 V MDmesh M2 power MOSFETs. The down-stream section comprises a DC-DC phase-shifted full-bridge converter based on MDmesh DM2 power MOSFETs and performs voltage step-down using an HF transformer, with a primary-to-secondary ratio chosen to maintain a sufficiently high efficiency and regulation over the entire operating range
