This user manual describes the basic procedure to correctly operate the 2 kW digital power supply evaluation board; order code STEVAL-ISA172V2. This system consists of an interleaved PFC circuit and an isolated full bridge phase-shifted DC-DC converter, designed to deliver 2 kW at 48 V with a maximum current of 42 A. The system operates with input voltages in the range of 90 V to 264 V AC and can be supplied both at 50 Hz and 60 Hz. The board is equipped with a fully digital control algorithm based on the STM32F334C8 microcontroller from the STM32 family. The PFC power stage is based on MDmesh™ M2 Power MOSFETs STW48N60M2 or STW48N60M2 -4 and on silicon carbide diodes. The DC-DC power stage is based on MDmesh DM2 Power MOSFETs STW35N60DM2 Additionally, the DC-DC converter is provided with an active clamp and a synchronous rectification (SR) stage managed by the microcontroller to achieve high conversion efficiency and allow adaptive control according to load levels.
