Abstract : This paper describes the design of a new configuration of direct power control DPC based on high selec-tivity filters HSF to achieve near-sinusoidal source current waveforms under different source voltageconditions. The proposed method uses the high selectivity filters instead of the classical extraction filterslow pass filters. The basic idea of the proposed DPC is to choose the best inverter voltage vector in orderto minimize instantaneous active and reactive power errors using two hysteresis comparators. Their out-puts associated with a switching table, control the active and reactive powers by selecting the optimalswitching states of the inverter. Simulation results have proved excellent performance, and verify thevalidity of the proposed DPC scheme, which is much better than conventional DPC using low pass filters.
