DISTRIBUTED LOGIC PARALLELING OPERATION OF THREE PHASE INVERTERS APPLYING SVPWM

Jian Chen

Abstract

The principle of the parallel operation of the inverters is analysed. Three control strategies for restraining the circulating current existing in the parallel system are proposed. The distributed logic control strategy for the three-phase inverter parallel system is presented. This strategy has been successfully applied to the power system where two three-phase inverters, each of them 35kW, 390V, 50Hz, operate in parallel. The load sharing is satisfactory.
