| Abstract |
A single-phase active power filter for high-order harmonic current compensation is presented in
this paper. In modern railway locomotives, multi-paralleled PWM converters provide unity power
factor operation with low THD, but their high-order harmonics current may provoke interference
problems to the railway tack signal and public telecommunication lines. A hybrid digital filter is
proposed to extract the harmonics reference currents compensated in active filters. A prediction
algorithm to compensate the delay problem that appears in the deadbeat current control is also
proposed to produce a predicted harmonics reference current. The effectiveness of the proposed
algorithms are verified through simulations and experiments. |
