  • Publication number: 20200007051
    Abstract: The present approach relates to a commutating circuit device (100) for reducing the load on at least one semiconductor of a converter (103). The commutating circuit device (100) comprises at least one first contact (105) and one second contact (110) for connecting to a battery (155), and also an intermediate circuit capacitor (115), which has a first capacitance and a first parasitic inductance (160), and the output-side converter (103). A second switch mechanism (130) and a third switch mechanism (135) of the converter (103) can be controlled by control signals. The commutating circuit device (100) also comprises the second serial connection (140) composed of a first switch mechanism (145) and a snubber (150) that has a first capacitance and a second parasitic inductance (165), wherein the second capacitance is lower than the first capacitance, and/or the second parasitic inductance (165) is lower than the first parasitic conductance (160).
