Abstract

A new compound energy converter for low earth orbit satellites is proposed, using the parallel power conversion technique, a new maximum power point tracking technique based on positive feedback, and the peak current-programmed control technique. These techniques are used for low EMI (electromagnetic interference), high power conversion efficiency, high reliability, stability and size reduction
