Abstract

This paper presents a multi output converter system that controls, simultaneously and independently, the separate buck converter and boost converter with the different specification by one DSP digital controller. As two separate converters are regulated by only one DSP, it is possible to achieve the simple digital control circuit for regulating the multi output DC-DC converter. By setting the software switch state, PI or fuzzy controller can be applied as a controller for each converter without any change of hardware. Also, PI and fuzzy control characteristics of each DC-DC converter is validated by experimental results.
