Abstract

Rectifiers consisting of parallel connected 6-pulse bridges with modulation in DC current circuit show properties of multipulse rectifiers. A load unbalance of the component bridges of 12-pulse rectifier approximates the space vector to the case of rotating one. In consequence the shape of the line currents is close to sinusoidal one. In this paper the topology of multi-pulse rectifier with modulation in DC current circuit is presented. The simulation results of investigations were obtained by means of the space vector for control of modulators. The laboratory results of investigations of 2 kVA power for 12 - and multi-pulse inverters have been presented.
