Abstract :
Presented is the design analysis of a single-phase grid-connected photovoltaic-inverter low-pass-output filter. It minimizes switching-frequency current harmonics, improving output response. The inverter is H-Bridge transformerless. Switching frequencies 8Hz, 14kHz, and 20kHz were compared for validation of the simulation and the experiment.
