With the proliferation of renewables and energy storage, inverters and converters are being updated to outperform their antecedents in every possible aspect for numerous applications in fields and industries. The proposed research involves the design and implementation of improved three interface converter, and B4-Inverter fed brushless direct electric current motor drive for industrial uses. The proposed integrated Three Port Converter (ITPC) and B4-Inverter fed Brushless Direct Current Motor (BLDC) drive is proposed targeting low or medium applications. The ITPC has been operated in unidirectional and going in both directions for accomplishing a built-in dual electric potential and power rate of flow control. besides, efficiency and the losses of the proposed converter are analyzed using three different domains, i.e., battery charging, discharging, and photovoltaic (PV) effectively. The results are validated by performing simulations of the proposed systems in MATLAB/Simulink. The validation results reveal that the proposed converter works under all three domains and that the losses in the PV domain are reduced compared to the other converters. Also, the average efficiency achieved is 80.95%. These results authenticate the application of the proposed converter to numerous applications pertaining to renewable energy resources and energy systems.
