Analysis on the Monopolar Three-Phase Solar Grid-Connected Current Source Inverter

Abstract

Article review the importance of the renewable energy system using solar energy. And the monopolar three-phase on current inverter model is established based the analysis of solar grid-connected inverter. With a work frequency period of power source, have been divided the 7 mould forms of 6 fan district and a switch period to alternate course with 0 ~ 1/3 π interval the method that describes control strategy specificly for example, for with I interval ( 0 ~ 1/3 π ) 7 alternate mould form is example specificly analysis system the realization of control method have gone on analyse comparatively in detail. Simulation results show that the system has the same performance comparing with theory analysis.
