APPLICATIONS AND MAIN PARAMETERS
Widely used in power electronic equipment for AC filtering.
It is used in high-power non-linear load such as converter, frequency converter and other converters, as well as power supply system with high harmonic content such as electric drive, welding machine, standby power supply, etc., to filter out high-order harmonic and improve power grid voltage quality.
It is connected with inductance, resistance and other devices to form an AC filter.
Provide low impedance channel for one or more harmonic currents and improve power factor.
