| Popis: | This paper presents an analyses of the leakage current (i cm ) of a mid-point voltage clamping H-bridge zero voltage switch controlled rectifier (HB-ZVSCR) transformerless inverter for grid-connected photovoltaic (PV) application. The circuit is constructed to reduce the ground current through two freewheeling switches, and four bridge diodes. The leakage current (i cm ) flows through the parasitic capacitor (C PV ), which is generated between the Photovoltaic (PV) panel, and ground. This paper shows the i cm characteristic in different condition for diverse C PV values. Further, the PLECS software simulation is shown with hardware implemented waveform for 1 kW rated power. Moreover, the measured i cm values are presented in a tabular form at different parasitic capacitors and switching frequencies. |
