Research on High Power Factor Control Strategy of Single-Phase Electroless Capacitor Variable Frequency Speed Regulation System

This paper mainly studies the high power factor control strategy of single-phase electroless capacitor variable frequency speed control system. The power factor of 0.977 can be obtained through matlab/simulink simulation. The single-phase non-electrolytic capacitor frequency conversion speed regulation system uses small-capacity film capacitors instead of traditional large-capacity electrolytic capacitors. It has the advantages of high power density and high input power factor on the grid side.
