Abstract :
This paper deals with a DSP based implementation of a new control method of a 3-phase active filter (AF) to compensate harmonics and reactive power of nonlinear loads. A current controlled voltage source inverter (CC-VSI) based configuration is used as the AF and PWM current control technique is used to derive gating signals to the devices of the AF. A 3-phase diode bridge rectifier with resistive-inductive loading is taken as the nonlinear load. Steady state as well as transient test results on a developed prototype are given to validate the new control method for the AF
