Digital Control of Single Phase Buck-Boost Converter by Pulse Amplitude Modulation Mehtod

PAM방식을 적용한 단상 승강압형 정류기의 디지탈제어

This paper describes a digital implementation of a pulse amplitude modulation(PAM) method for a unity-power-factor buck-booster converter. A digital controller is designed and implemented by a Digital Signal Processor(DSP) to replace the analog control circuit for PAM. Experimental results are presented and compared with simulations.
