Abstract :
This paper deals with the performance analysis of an improved converter which is capable of supplying reactive power of other 3-phase linear loads at the common point of connection to the AC mains. The converter with sinusoidal unity power-factor input currents can provide regulated DC voltage to feed applications such as adjustable speed drives (ASD). It employs a PI based DC voltage controller and carrierless PWM hysteresis current control. A detailed dynamic model of the scheme is developed and simulated to study the effect of changes in DC and auxiliary AC loads
