SMOOTHING KICKING COILS (CHOKES)
Smoothing kicking coils (chokes) are the kicking coils designed to be switched on in series to DC circuit in order to reduce current ripples. Smoothing kicking coils (chokes) are used in the output circuits of rectifiers, where they ensure significant ripple limitation of the rectified current. Often capacitors are connected to smoothing kicking coils thus creating LC filters.
The advantages of using the smoothing kicking coils manufactured by Pskov Power Transformer Factory are as follows:
They decrease the rate of current rise at short circuits
The units protect against the in-rush currents in the converter capacitor battery during voltage pulsed spikes in the network
They reduce voltage ripple in the DC link under the input voltage asymmetry
