Tuned Harmonic Filter
The tone filter is suitable for power electronic devices such as DC and AC motor drives, battery chargers, UPSs and any kind of diodes and thyristor rectifiers, to reduce the harmonics of reconnecting these electronic devices to the network. Using the tunable filter and the declared conditions, the harmonic can reduce the current to less than 5, 10, and 15 percent.
