TS Line Chokes serve for suppression of adverse effects generated by some appliances to the electric network. Typical examples of such appliances are controlled and uncontrolled rectifiers, switched sources and frequency converters. By inserting a line chokes between the appliance and the network connection we suppress commutation effect and current surges caused by capacitance in DC circuits, and also suppress EMI caused by switching of power semiconductor components. Using of line chokes also increases the effect of noise suppressing filters. The line chokes are designed so that they are equivalent to supply transformers with ek = 4% at voltage 3 x 400V/230V and frequency 50 Hz. The design also respects all operational statuses of converters, both: static and dynamic.
