DC Choke is an inexpensive way to filter and control the DC bus voltage and current in a variable-speed drive/inverter. They help to absorb spikes in the DC bus voltage and reduce harmonic distortion in the AC input line current. DC chokes are found inside the drives and are fitted in pairs.
DC Choke Working is by restricting the flow of harmonic currents or high frequencies. From the perspective of harmonic mitigation, DC chokes perform similarly to AC line reactors. Both of them contribute to lowering the drive input current's peak value.
DC Choke Design is done in such a way as to make it unique from line reactors. Dc link chokes have the benefit of increasing circuit inductance for power quality concerns without lowering the voltage of the AC input line. Link chokes are normally used on the positive DC bus, but they can also be used in pairs, with one on each of the positive and negative buses.
DC Choke Price is affordable and pocket friendly at the same time.
