Abstract
Front end AC to DC converters of the boost type are used in traction applications for generating the DC link for the inverters. A GTO based converter is usually switched with a switching frequency of 300 to 500Hz, resulting in low frequency harmonic problems. In order to avoid this, multiple converters with phase shifted carrier signals are used to suppress the low frequency harmonics. A detailed study of an AC to DC converter, parallel operated with reduced sensor and improved power-factor in light load conditions is presented in this paper.
