An Integrate Modeling and Controlling of DC-DC Boost Converter Topology

In this study, an integrate modeling and controlling of DC-DC boost converter topology is proposed. The traditional DC-DC boost converter topology has the major drawback such as the input power supply is an unregulated rectified voltage and the load on converters is affecting the effectiveness of the converter. The proposed boost converter topology is differed from the traditional boost converter topology by addition of the auxiliary switch, coupled inductor, clamp capacitor and feedback controller. The presented auxiliary switch, coupled inductor produces the ripple free input current, soft switching like zero voltage switching and zero current switching. The feedback controller control the operation of the main and auxiliary switches, which generates the controlling pulses by using the input parameters the input current and output load voltage as the input parameters. These actions can enhance the converter efficiency and voltage gain. Then the proposed converter is implemented in the MATLAB/simulink platform and the effectiveness is analyzed by comparing with the different converter topologies. The comparison results demonstrate the superiority of the proposed approach and confirm its potential to solve the problem.
