Back to back (B2B) voltage source converter is used for HVDC system and ac drive system to control active-reactive power. In this paper reduced switch back to back converter is used for induction motor drive system which is operated in unity as well as leading power factor. Active and reactive power flow are independently controlled. The active power transfer is controlled by angle delta; where delta...
This paper presents an application of nine switch converter (NSC) for power factor improvement of 3-phase supply. Power factor improvement is achieved by controlling DC link capacitor voltage. To control capacitor voltage PID controller is used. Modified pulse width modulation with third harmonic injection technique is incorporated in NSC. An angle delta; between grid voltage and rectifier reference...
