Abstract
SummaryA newly designed generic photo‐voltaic (PV) DC‐DC/DC‐AC converter is for direct current (DC) grid or single‐phase alternating current (AC) grid integration. Main concept of the proposed converter is universal power conversion, and the same converter is used for DC‐DC/DC‐AC applications which also aiming for minimum redundancy because the proposed converter can be able to produce DC and AC output from the fixed/variable DC source. The proposed converter is designed with single‐stage dual leg topology, with a designed filter, and protection circuits are connected in output/grid side. The proposed circuit is compared with existing topologies, and comparative analyses are made in both chopper (DC‐DC) and inverter (DC‐AC) modes for universal or generic operation. Real‐time implementation of the proposed model is prepared for the power rating of 3.5 KW during inverter mode and 4 KW when same circuit working in chopper mode. Hardware results are obtained from the model from both chopper and inverter modes. Finally, correct applications, advantages, and future work are concluded in the last section.
