Stover, J B

A commercially available single-phase line-commutated inverter has been tested in a photovoltaic power system. Efficiency and power factor were measured as functions of solar array voltage and current. Also, the effects of input shunt capacitance and series inductance were determined. Tests were conducted from 15 to 75 percent of the 8 kW rated inverter input power. Measured efficiencies ranged from 76 percent (at 160 V and 8.0 A) to 88 percent (at 200 V and 18.7 A) at about 50 percent of rated inverter input power. Power factor ranged from 36 percent (at 160 V and 8.0 A) to 72 percent (at 200 V and 28.6 A).
