Implementation of heric transformer-less inverter with multiple sources

Abstract

In this paper, the implementation of HERIC transformer less inverter with variable energy sources as input is discussed.In order to get better efficiency, instead of using normal inverter transformer-less HERIC inverter had been used. The HERIC inverter contains fewer amounts of leakage current and conduction losses. Due to various climatic conditions, anyone of the energy sources (solar/wind) deliver low power. At that condition, the proposed structure is used to compensate the load requirement with the useful of battery. UP-PWM modulation is used in this proposed work.The performances were examined by using MATLAB/Simulink software. The hardware implementation of the proposed model is also discussed.
