摘要

介绍了一种高频pwm总线分布式电力系统的设计思路和实现方法。该系统采用100 kHz, 48 V峰值PWM总线进行交流电压分配。负载变换器由不同电平的输出磁放大器后稳压器组成。母线调节是通过一个简化的前端设计完成的，该前端设计由一个升压PFC变换器级联一个双开关正激变换器组成。给出了5 V直流和3.3 V直流下200w输出的实验结果。

A high-frequency single-side PWM multiple bus distributed power system

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.
