Simulation Research on One-Cycle Controlled AC-AC Cuk Converter

Abstract

AC-AC Cuk Converter which constituted by bidirectional switch has an advantage of high transmission efficiency, but most of them usually use open-loop control. In this paper, we propose one-cycle control of the AC-AC Cuk converter. The operating principle and control method are presented. The simulation results based on Matlab are given to verify its rationality and feasibility. Compared to common PID control, it has excellent control performance. Furthermore, one-cycle controlled AC-AC Cuk converter has the ability to reject input voltage perturbations and faster dynamic response.
