PIWPDOCS/KMH(X) Specficanons/20556300 - I medmens i June 2(9 doc I M 96209 HIGH EFFICIENCY PHOTOVOLTAIC INVERTER A photovoltaic (PV) inverter (30) includes a single DC to AC converter configured to operate solely in a buck mode for PV array voltage levels greater than a connected power 5 grid instantaneous voltage plus converter margin, and further configured to operate solely in a boost mode for PV array voltage levels plus margin less than the connected power grid instantaneous voltage, such that the PV inverter (30) generates a rectified sine wave current (32) in response to the available PV array (12) power, and further such that the PV inverter (30) generates a utility grid (14) current in response to the rectified sine wave 10 current (32).
