Abstract

One of the key elements in transferring the power from the distributed renewable energy resources into the power grid is the single-phase inverters. However, due to the operation principle of inverters, they generate high-frequency switching components that causes a distortion in the injected current at the grid/load side. In order to suppress this problem, the $LC$ filter is typically used. In this paper, equations are presented to calculate the LC filter parameters in a grid-connected single-phase full-bridge inverter operated based on bipolar switching method. According to the derived closed-form equations, inductance value of LC filter is independent of the modulation index. Furthermore, it is demonstrated that the angle at which the maximum peak-to-peak current ripple occurs is always the zero crossing of output current. However, the value of the peak-to-peak current ripple varies based on the modulation index and time. To validate the derived equations, a 6.6 kW single-phase inverter is simulated and results of two case studies for 110 Vrms and 220 Vrms are provided.
