  • Publication number: 20240162816
    Abstract: A circuit arrangement and a method with a DC voltage supply, a DC voltage intermediate circuit, a power converter, a control device for the power converter, and with a braking resistor. The power converter is formed as a multi-phase bridge circuit having at least one, preferably at least two first half bridge circuit(s) and having at least one, preferably at least two second half bridge circuit(s), which are each connected to the DC voltage intermediate circuit. A first resistor terminal of the braking resistor is connected to the middle tap of the first bridge circuit, and wherein a second resistor terminal of the braking resistor is connected to the middle tap of the second bridge circuit.

  • Publication number: 20230261589
    Abstract: Load bridges (2) of an inverter unit (1) include load branches having semiconductor switches (4, 5, 15, 16), that have a node point (6) which is connected to a load (7) and to two different potentials (P1, P2). Node points (6) are connected via a first resistance circuit (8) to potential (P1). Node points (6) are further connected via second resistance circuits (9) to tap-off points (11). The tap-off points (11) are connected via third resistance circuits (10) to the other potential (P2). At each of the tap-off points (11), a potential (U1, U2, U3) is tapped-off and is fed to a monitoring device (12). The monitoring device (12) determines the difference (U1?) between the tapped-off potentials and the second potential (P2). The control device (3) considers the signals (M1, M2, M3) for the actuation of the load bridges (2).

  • Publication number: 20220368240
    Abstract: A power semiconductor module has a substrate that has an electrically non-conductive insulating layer and a first metal layer on the insulating layer and forms conductor tracks, with power semiconductor components arranged on the first metal layer and electrically connected to the first metal layer and having a DC voltage connection device that has a first, second and third flat conductor connection element that are arranged on an end region of the power semiconductor module and that are electrically conductively connected to the first metal layer. During operation, the first and second flat conductor connection elements have a first electrical polarity and the third flat conductor connection element has a second electrical polarity.
