The analysis, design, and performance of a prototype high-power-density converter suitable for use in the front-end of a distributed power supply system is presented. It delivers 1 kW to a regulated 40 V distribution bus from the rectified utility. Its switching frequency is 500 kHz, and it uses a phase-shifted PWM (pulsewidth modulation) technique to avoid primary side switching losses.>
