In this proposed system, the design of a controlled DC-DC boost converter for PV charger application is presented. The duty cycle of the designed boost converter, which operates at 50 KHz, is controlled directly to track the maximum power point of the PV panel that is changing in response to variation insolation of a sunny day. The designed Boost converter is used as an interface unit for matching a 24V battery bank (20AH, 12V, C/5) with a Solar panel. The overall system is built and validated by using MATLAB SIMULINK. The simulation results show that the average efficiency of the proposed MPPT-controlled DC-DC converter is with good result which is calculated by comparing the tracked PV power by the designed converter and the proposed maximum power of the panel for different levels of insolation. The results express the effective operation of the designed converter system by tracking MPP for PV panels in different insolation situations.
