A High Efficiency and High Step Up Solar Fed Coupled Inductor Converter for PMDC Motor Drives

Abstract

An efficient DC/DC converter with soft switching topology is proposed in this paper. This converter efficiently utilizes the energy stored in the passive elements to improve the performance of the Boost converter. With the interest in the utilization of renewable energy resources that is available in huge amount in our country, the proposed converter is powered by the solar photovoltaic system. And further, the proposed converter is applied for drive applications wherein the Permanent Magnet DC motor (PMDC) is used to drive the load. In addition, the semiconductor switch used in the proposed system is controlled by the Triangular Pulse Width Modulation (TPWM) Strategy. And also, the switches with low on state resistance are used to reduce the conduction losses. The design and modeling of the proposed DC/DC converter is simulated by using MATLAB tool and the results are analyzed and discussed in the fore coming chapters.
