LOAD BALANCING AND POWER FACTOR CORRECTION FOR MULTIPHASE POWER

In recent years the area of multi-phase (phase order more than three) machines is popular. A multi-phase source may be derived from transformer connection (3- phase to 4-phase) or by DC link 4-phase inverters. There are problem of unbalance, harmonic distortion and poor power factor operation. This paper proposes the supply side load balancing and power factor correction .The proposed compensation scheme uses the shunt current source compensation whose instantaneous values are determined by the instantaneous symmetrical component theory. An ideal compensator in place of physical realization of the compensator has been proposed in form of a current controlled voltage source inverter. The compensation schemes developed in the paper are tested for their validity on 4-phase (4-wire & 5-wire) circuits through extensive simulations.
