The scope of our capabilities includes smoothing reactors and DC reactors (chokes) for connection in the intermediate circuit (DC Bus) of power converters. This type of reactor is required to smooth and stabilize the DC current. It can prevent undesirable sharp rise and decrease of DC bus current as well as prevent interrupted flow of DC current by smoothing and maintaining continuous flow of lower ripple DC current. The natural electromagnetic property of these reactors enables them to restrict rapid changes in current and thus stabilizes the current through the DC circuit.
