摘要

It is crucial to retain power balance with fluctuating AC voltage, in a standalone solar photovoltaic (S-PV) system. In this manuscript the DC side battery support, has applied by using the power balance loop and DC-link voltage droop technique. For efficiently power transfer a transformer-less arrangement of 7-level cascaded H-bridge multilevel inverter (HBMI) has used with LC filter. The sliding mode control method has been employed to successfully track the reference/set AC voltage as well as stabilizes the power irrespective of load variation. The standalone S-PV fed cascaded HBMI through battery interface has assessed make use of the simulations out of PSCAD software and conduct test carried applying FPGA based device.
