Reference designs

2-kW industrial AC/DC battery charger reference design with 92% full-load efficiency

This reference design is a module that can be set as standard power supply or a battery charger. The output voltage ranges from 0 V to 32 V at a maximum current of 62.5 A. It consists of four boards, a boost PFC, a phase shift full bridge, a small daughter board (hosting the microcontroller), and a (...)
