Abstract

Design considerations of a zero voltage switching forward AC-DC PFC (Power Factor Correction) converter are presented here .The converter can achieve high PF in the entire universal input range. The forward converter topology also ensures that isolation of input is achieved and a novel single stage power factor correction circuit is realized. The converter is forced to operate in critical conduction mode (CRM) with the help of an improved constant on-time control. To confirm the validity of the proposed converter, simulations have been done using MATLAB/SIMULINK and are presented here.
