In this paper, the transient operation of four leg voltage source converter (VSC) under unbalanced load conditions is investigated. The inverter is particularly interesting for simultaneous supply of three phase and single phase load in transformerless Hybrid Power System (HPS) application. A control strategy for the VSC based on the decomposition of the supply voltages and currents into instantaneous positive, negative and homopolar sequence components is described. The three sequences are controlled using two different rotating reference frame systems, so that the disturbance of the output voltage due to the load unbalances is eliminated. Simulation results are presented to verify the transient operation of the VSC under unbalanced load conditions.< Leer menos
