| Research Abstract |
In this project, high-performance inverter for distributed energy source using hybrid filter is proposed. The proposed inverter maintain high performance both under grid-connected and islanding situation. At first, the efficiencies of the proposed inverter applied different control algorithm were considered. From theoretical analysis ans experiments, it is derived that unipolar hysteresis control can improve efficiecny approximately 3 percents. In order to realize high-performance, linear amplifier of the hybrid filter is controlled as a negative capacitance in islanding mode and a dumping resistance in grid-connected mode.
