Different Control Method Approaches to a Non-Inverting Output Voltage Based Bridgeless PFC Cuk Topology Cascaded with Flyback Converter

Abstract

A typical control system aims to generate a control output which has to force the system in order to keep it on desired level or position. In power electronics, control systems, are using to obtain a fixed steady state voltage or current on the output terminal. In general, there are two control methods: Open loop control and closed loop control. The most significant difference between these two methods is feedback, which provides an information to input of the control system and makes the system reactive for varied conditions. There are also different types of closed loop control. These two are PI and PR controlling systems. A PR controller has infinite gain at the fundamental frequency which makes it possible to achieve zero steady state error rather than a PI controller. In this study, the stability and transient time differences between these two control strategies are introduced on a modified cuk converter, which powered with an AC source and has no bridge at the input side. All the methods and propositions are verified on MATLAB Simulink environment.
