Abstract
Integration of solar photovoltaic (PV) systems into a microgrid is accomplished with the help of a dual-diode, dual-capacitor, and single-switch DC-DC boost converter. At the output, a power of 400W transfer is achieved together with a voltage gain of 3.92. The converter may be operated in two primary forms, both of that are based on the ON/OFF switches. The benefits that may be noticed in practice from the hardware output are high reliability and decreased switching losses. The properties of the converter are determined via an open loop system that uses pulse width modulation (PWM) switching at 20 kHz. An examination of the step response is carried out. The validations of the proposed converter topology has been compared with the recent converter topologies. The performance of the converter has been evaluated in terms of voltage gain.
