| Abstract: | This paper describes the function on output filter in inverter to reduce the produced output harmonics,the transient oscillations on the traditional LC filter has been analyzed.The method of the virtual resistor has been applied to the filter and its principle is analyzed.The paper compares the new strategy with the old one.A virtual resistor is an additional control algorithm that simulates the roles of a resistor in the output LC filters.Then the Theory analysis and the simulation results have verified this improved method in output filter is simply and efficiency. |
