PV Based Hybrid Boost DC-DC Converter for Induction Motor Applications

Abstract

 Due to the increasing need for the electrical energy and due to the depletion of conventional sources of energy along with the rising cost of those, renewable energy resources are getting more importance. When solar energy is considered, electricity production from it, is very eco-friendly and available in plenty in nature. The high cost of PV panels and its low efficiency limited its use earlier but with the increase in technology the efficiency of solar cells are also getting increased which encourages the use of PV system in present days In this paper a new Hybrid DC-DC converter with PV input is presented, this converter has high voltage gain where the input is 50V and the output is 600V. This converter is designed based on the topology of neutral clamped Inverter. This DC-DC converter mainly solves the problem of voltage mismatch between PV source and grid. This converter uses one inductor and two capacitors connected in series are the cause for obtaining High voltage gain. PWM method is used to ON and OFF the Power Electronic Switches of the converter. The output of the proposed DC-DC converter is inverted and then fed to Induction Motor Drive.
