Development of a Grid-Connected Microinverter Based on the Integration of the CUK Converter with a Switchgear Structure

The main focus of this research work is on designing the dimensions of the proposed DC-DC and DC-AC converters. Since it is an unprecedented DC-DC converter, it is important to enable the DC-DC converter to enable simulations in PSIM software. In addition, the size of the proposed DC-AC converter was provided for the purpose of making simulations and specifying the actual components for implementing the 180 W prototype, with the current flowing into the phase. In addition, simulation results are obtained, which show that it is possible to find the maximum power point of the PV module by implementing the MPPT algorithm without having to measure the current of the PV module.
