Abstract

The 6-pulse controlled AC/DC converter produces harmonics. The input current total harmonic distortion and the input power factor, which is firing delay angle dependent, are major drawbacks, and a compensation technique is mandatory. This paper introduces a compensated 6-pulse current sourcecontrolled rectifier with a shunt active power filter (APF ) in different configurations. The shunt APF with predictive current control is coupled to the 6-pulse systems in three different compensation configurations. The APF is connected either directly to the front-end transformer primary or secondary side or via a transformer to reduce the filter side voltage. The comparison between these configuration is introduced; each configuration has merits and demerits. The comparison cannot be genuine. Simulation results are presented for a medium voltage converter which is scaled to allow low-voltage experimental confirmation.
