Zero-crossing distortion has been observed in the ac output current produced by some grid-connected photovoltaic inverters and this can cause a resonant response between the grid impedance and the inverter filter capacitor. In some cases, particularly with large numbers of parallel-connected inverters and with weak grids, the resonance can cause voltage …

A power inverter, inverter, or invertor is a power electronic device or circuitry that changes direct current (DC) to alternating current (AC). The resulting AC frequency obtained depends on the particular device employed. Inverters do the opposite of rectifiers which were originally large electromechanical devices converting AC to DC.
