디지털 제어기에 의한 강압형 및 승압형 DC-DC 컨버터의 동시제어

Abstract

This paper presents a one digital controller two topology PWM DC-DC converter that controls, simultaneously, the separate Buck converter and Boost converter with the different specification by using an inexpensive and efficient 8 bit micro-controller. One timer interrupt is used for the detection of output feedback voltage, and other two timer interrupts are used for the generation of PWM waveform for Buck and Boost converter. The control characteristics of one digital controller two topology PWM DC DC converter is validated by experimental results.
