Abstract

This paper is described a digital implementation of a pulse area modulation (PAM) method for a unity-power-factor buck-boost 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.
