摘要：
An apparatus and method for reducing certain harmonics in the output of static inverters. Static inverters which employ a switching device arranged in a bridge circuit to convert direct current power to alternating current power produce undesired harmonics in the output of the inverter. Harmonic neutralization techniques are further improved by the invention utilizing selective notching of the inverter pole voltage and a coordinate phase shift between the set of pole voltages produced by the individual inverters. The notch angles in the individual pole voltage outputs are chosen to minimize or eliminate specific undesired harmonics.
