A power factor correction (PFC) plays a major role towards the improvement of systems quality and stability, as well protection control performance. This paper presents novel method for automatic (APFC) based on coherence approach. In this method, original required reactive compensation can be determined using cross-coherence coefficients evaluated between voltage current signals. Beside auto-c...

Abstract This paper analyzes the influence of harmonics on system and importance power factor correction. According to requirements aircraft use, an active correction based three phase six switch topology is designed. The article working process control method system, then designs a rectifier convert 220V/400Hz AC provided by DC high. Moreover, performance tested.
