“…This in turn causes pulsations to occur in the torque generated by the motor resulting in noise and vibration. Active filters are generally employed to reduce the harmonics either in the primary AC line or in the DC voltage in systems such as traction [3][4] and power systems[5]- [7] and to overcome the limitations of passive filters. The control method used for the PWM converter (CNV in Fig.…”

In single phase fed traction systems the supplied single phase AC is converted to DC, using AC/DC converters, and then to three phase AC using DC/AC PWM inverters for driving AC motors. In this conversion process, however, the DC voltage contains a ripple with a frequency equal to twice that of the single phase AC supply frequency. This fluctuation introduces disturbances in the PWM inverter output current supplied to the AC motor and causes other negative effects. In this paper, these negative effects are discussed and a new DC active filter is proposed to reduce the ripple in the DC voltage of the motor drive. The proposed filter's control is of the feed forward type. In this control, the ripple power of the smoothing capacitor voltage is calculated and used to generate a compensating current to minimize the ripple power. Simulation results for a 1,500kVA model and experimental results for a 1OkVA mini-model system which confirm the operation of the active filter will also be presented.

“…The idea of active filters, which has been discussed and tested in stationary power systems 5,6,7,8) , is another alternative to the problem. The closed-loop threephase power active filter is considered as a successful tool to totally compensate for harmonics and reactive power.…”

To study the problem of the injected harmonic currents into the overhead line by the modern AC rolling stock, a mini model is presented. A Hybrid Active Power Filter composed of a controlled PWM converter in series with a passive filter is proposed for the compensation of the injected harmonic current. Finally, the results of a two control strategies for the generation of the compensating reference are presented.
