<p class="Abstract"><span>This paper discusses the Power Factor Correction (PFC) for single phase ACDC Buck-Boost Converter (BBC) operated in Continuous Conduction Mode (CCM) using inductor average current mode control. The proposed control technique employs Proportional-Integral (PI) controller in the outer voltage loop and the Inductor Average Current Mode Control (IACMC) in the inner current loop for PFC BBC. The IACMC has advantages such as robustness when there are large variations in line voltage and output load. The PI controller is developed by using state space average model of BBC. The simulation of the proposed system with its control circuit is implemented in MatLab/Simulink. The simulation results show a nearly unity power factor can be attained and there is almost no change in power factor when the line frequency is at various ranges. Experimental results are provided to show its validity and feasibility. <br />Keyword</span></p>

In this work, the analysis of a CD-CD converter type Boost is presented. This converter works in Discontinuous Conduction Mode; In addition, the design of its control loops is performed, using an Average Current Mode control. The Boost converter is part of a photovoltaic generation system using solar panels. The photovoltaic system is established in a microgrid, with which the inverter works in grid mode and island mode. The main objective of the Boost convertor is to raise and regulate the voting from the solar panels to feed a single-bridge full-bridge inverter. The controllers designed for the boost converter are validated by simulation. The results obtained prove that the designed controller has an acceptable transient response to disturbances in the system input and adequately analyzing overdrafts and establishment times when disturbances are generated.
