Solar PV Based Zeta Converter with Capacitor Multiplier and Coupled Inductor for DC Drive Application

In this paper performance of DC drive fed by high step-up converter is studied. High step up zeta converter is employed here with solar PV as a source without Extreme duty ratios and the numerous turns-ratios of a coupled inductor , converter achieves a high step-up voltage-conversion ratio and the leakage inductor energy of the coupled inductor is efficiently recycled to the load. These features explain the module's high efficiency performance. The operating principles and steady-state analyses of continuous and boundary conduction modes, as well as the voltage and current stresses of the active components, are analyzed for a 250W circuit model using MATLAB SIMULINK.
