Comparing capacitive and LC compensators for power factor correction

A method is presented for finding the optimum fixed LC compensator for power factor correction of nonlinear loads where both source voltage and load current harmonics are present. The LC combination is selected because pure capacitive capacitors alone would not sufficiently correct the power factor. Optimization minimizes the transmission loss, maximizes the power factor and maximizes the efficiency. The performance of the obtained compensator is discussed by means of numerical example.
