Abstract

The solar energy rectifier plays a key role in electric energy conversion from DC power to AC power supply that can be fed directly into on grid. Nowadays, power inverters are being used in power conversion process but these devices face with challenges like inefficiency and insensitivity. This paper, proposed an efficient and controlled solar power electronic converter (ECSPEC) in microgrid and smart grid applications. The two PV arrays with 1000Watts per square meter each, solar generated current of 3.80Amps (A), diode voltage of 0.7Volts (V) and diode saturation current of 3.15e-7A each, drain-source current of 15A of Metal-Oxide Field Effect Transistor (MOSFET), gate-source voltage and threshold value of 10V and 1.7V of MOSFET each respectively, capacitor filter of 1e-6 farad were considered. The MATLAB/Simulink 2019a was used modeling and simulation. The EC-SPEC efficiency was developed in 2 self-regulating approaches. Firstly, AC output power to DC input power ratio was compared within one AC cycle. Secondly, system losses were calculated by single component using SIMSCAPE Logging. The models were used to simulate each full AC cycle for a provided amount of solar irradiance, as well as the effective DC voltage and AC root-mean square current. The results shows that output power control and synchronization were attained through MOSFET control, and optimized parameters such as 348VDC, 20A, 100VAC, and 96.72% efficiency have been ascertained utilizing efficient and integrated single-stage converter characteristics. Finally, the proposed EC-SPEC demonstrated the better performance with compared to the existing devices for efficiency, sensitivity and reliability considerations.
