Abstract

The design and implementation of a high-frequency AC distributed power system is presented. The system utilizes a 300 kHz, 50 V peak soft-transition square wave for AC voltage distribution. Load converter designs consisting of 50 W regulated resonant rectifiers yield sinusoidal bus currents. This, coupled with the soft-transition bus voltage wave shape, reduces the potential for noise interaction with the host system. Bus regulation is accomplished through a simplified front-end design consisting of a boost PFC converter cascaded with a soft-switched half-bridge inverter. Experimental results are presented for operation at 5 Vdc and 100 W output
