Abstract

An approximate procedure for on-line computing the loss-optimal values of the switching angles in a class of pulse width modulated converters is presented. The proposed technique is independent of the constants of the circuit and allows one to obtain a given power in the DC load with minimum loss of energy in the AC and DC filters. This corresponds to have a quasisinusoidal supply current with minimum ripple on the output load. Simulation and experimental results confirm the practical feasibility of the method
