A New Method Used to Eliminate the DC Component of Grid-Connected Inverter

Abstract:

Due to the impact from the conditioning circuit, it is easy to generate DC component for the reference voltage when the digital signal processor (DSP) sampling the grid voltage. It cannot eliminate the DC component for the grid inverter based on feed-forward decoupling control, and this would bring the DC component to the inverter voltage. The traditional DC component elimination method includes two aspects of hardware and software. This paper presents a new method to eliminate the DC component. The simulation results show that the algorithm is correct by using PSCAD/EMTDC.
