Abstract: This paper presents a reducing method of higher harmonic currents using an active filter at an ac side of condenser input type three-phase diode bridge rectifier. The three-phase PWM inventer is connected in parallel to rectifier as an active filter. The principle of the active filter is to cancel higher harmonic currents contained in load current by injecting reversed phase harmonic currents into the voltage source side. In this system, optimal servo controller is used to reduce higher harmonics at current controller. Root locus method are used to obtain optimal weighting factor of a performance criterion and to select control method. Servo controllers with three types of compensating element are simulated to show the compensation performance. Servo controller with dead time and feedforward compensation is compared with PI current controller. Finally, power spectra of a load side current and a source side one are shown. Simulation results are shown to verify the usefulness of this system.
