Abstract
The development of distributed generation (DG) systems has led to the increasing use of voltage source inverters. However, step-changes in the modulated voltage can produce dangerous peak common-mode currents (CMCs), which can interfere with the power system ground and cause detrimental effects on other equipment. In this paper, the root cause of CMCs is explored and analyzed. After this, a new method which combines of a modified inverter topology and a predictive current control scheme is developed. The test results show that the proposed method effectively controls the load current while the CMCs can be reduced significantly.
