Z-source DC- DC Converter for Low Power Application in Micro Grid Operation

Abstract

Nowadays DC-DC converters are widely used in Microgrids for synchronization of distributed generators with AC and DC power lines and for low power applications. Therefore it becomes very necessary to improve the performance of AC-DC convertor The main emphasis is given on power factor improvement on supply side. To achieve this Z-source AC-DC power convertor is proposed in this project. By using Z-source at the input side transient response of convertor gets improved and power factor is obtained nearly equal to unity. Proposed scheme uses ferrite core high density , high frequency transformer . For the proposed scheme results are obtained by simulation and simulation results are validated with the hardware results.
