Abstract

This invention is related to a single phase inverter which enables converting the direct current voltage to alternating current voltage, allowing the energy obtained from photovoltaic (PV) panels to be transferred to the voltage of the grid, connecting to the grid voltage without using a transformer, keeping the leakage current below the standards and keeping the efficiency (ratio between output and input powers) at the rated power value up to 96 %.
