Compensated medium voltage 6-pulse csr using shunt active power filters : three different configurations

Abstract EN

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 source controlled 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.
