DC Component Output Control for Switching-Nodes Preset SPWM Inverter

Xie Shaojun Yan Yangguang (Department of Automatic Control)  
Because of the variations of power devices, DC component is contained in the output voltage of the switching-nodes-preset SPWM inverter. The DC component would effect the normal functions of neutral forming transformer and the electric equipment. Apart from selecting suitable power devices for making the inverter,a one-phase closed-loop adjusting circuit is necessary to control the value of the DC component. In this paper, the cause and effect of DC component are analysed,the principles of DC component control are introduced and the design considerations are given from the viewpoint of modifying the control signals of power transistors and designing the circuit. The experimental results verify that the method of DC component control used in this paper is feasible.
