Control Strategy for CCM Boost Converter and Dual-Loop PI Regulator for Variable Load

Abstract. This paper presents a comprehensive analysis of a photovoltaic (PV) energy conversion system equipped with a DC–DC Boost converter and a variable load. The objective is to develop a complete PV generation system including a Boost converter controlled by a dual-loop PI regulator. The control architecture in this work consists of an external voltage loop and an internal current loop. The MPPT controller can be implemented using different methods and algorithms.In our case, we merged an MPPT algorithm with a cascade controller. This combination improves system performance and provides good responses compared to other MPPT control techniques without a controller. This proposed controller is used to control the boost converter in order to maximize power transfer regardless.
