Abstract
Thyristor Bridge rectiﬁers are employed to obtain dc regulated voltage from ac main. These rectiﬁers are inject harmonics in the utility, it has been overcome by passive or active filter but it is costly and bulky.This paper presents three phase AC to DC boost bidirectional converter using DQ theory based current control loop. This converter provide constant DC boost voltage from 3 phase AC voltage by closed loop control. This converter has boosted DC voltage with unity input power factor and harmonics free source current. Results are obtained by computer simulation/MATLAB.
