Abstract :
The paper deals with line-frequency commutated rectifiers, providing compliance with IEC 1000-3-2 standards with a reduced overall reactive component size as compared to conventional rectifiers with passive L-C filters. Based on a previously presented high quality rectifier, different topological modifications are studied with the attempt to reduce the magnetic component volume and/or to improve rectifier performances. The low switching frequency accounts for reduction of losses and of electromagnetic noise emission as compared to high switching frequency rectifiers. Moreover, the switches operation results in a boost action, which compensates for the filter inductor voltage drop, thus providing output voltage stabilization against load variations
