Abstract

This paper presents a multi-output power converter system that controls, simultaneously and independently, the separate buck converter and boost converter with the different specifications by using one digital controller and fuzzy algorithm. As two separate converters are regulated by only one DSP, it is possible to achieve a simple digital control circuit for regulating the multi output DC-DC converter. The inference procedure of the fuzzy controller is included. The control characteristic of each PWM DC-DC power converter is validated by experimental results
