Abstract

The design consideration and implementation of a high frequency (HF) PWM-wave bus distributed power system (DPS) is presented. The system utilizes a 100 kHz, 48 V peak PWM bus for AC voltage distribution. The load converter consists of different level output magamps post-regulators. Bus regulation is accomplished through a simplified front-end design consisting of a boost PFC converter cascaded with a two-switch forward converter. Experimental results are presented for operation at 5 V DC and 3.3 V DC with 200 W output
