Abstract:

Conventional energy generation methods and environment protection are two faces of a coin that never go hand in hand. The growing requirement in energy hence increased the importance of the renewable resources. In this scenario, inverters capable of handling this type of resources are also in demand. The inverters for renewable energy harvesting usually have multiple number of power stages that adds to the losses, affecting the efficiency of the entire system. In this work a new type of ac/dc single phase transformer-less inverter topology with single stage operation and battery charging capability is proposed. Inverter uses both buck and boost operation to handle the variable nature of the input. The battery charging is done using buck operation. The principle of operation is demonstrated through the analysis of equivalent circuit. Proposed Inverter uses instantaneous power type controlling using PI controller. A 220 V, 50Hz, 2000W simulation model was studied using MATLAB simulink and the study showed that the usage rate can be increased by incorporating the battery charging within the inverter.
