Abstract

Abstract:

The control strategy based on virtual power grid flux without power grid voltage sensors is proposed to improve reliability and reduce cost for the gridconnected inverter. A novel control strategy makes the DC voltage flexibly run in parallel based on multiple armaturewinding, making the system more reliable and robust. Experimental results show that output currents are sinusoidal, with a good dynamic and static performance. Thus feasibility of the control strategy is verified.

Key words: multiple armature winding; parallel; sensors without grid voltage; virtual grid flux
