| Abstract |
This paper describes a novel control strategy of a direct-power-control based indirect matrix converter. The key of this strategy is direct selection of a switching state of the indirect matrix converter on the basis of instantaneous power errors. A relationship between the instantaneous power and the switching state of the indirect matrix converter is theoretically analyzed, which is essential to compose a switching-state-table. Effectiveness of the proposed technique is examined through several experimental tests, using a 1.6-kW prototype. As a result, unity power factor operation is achieved by the proposed method, and the output currents are confirmed to be sinusoidal waveforms without large distortion. |
