  • Patent number: 11271495
    Abstract: A power converter arrangement includes a first converter and a second converter which include each an intermediate voltage circuit and a load-side converter. The intermediate voltage circuit of the first converter is connected electrically to the intermediate voltage circuit of the second converter by a connecting line. The connecting line is connected to a node point either with three partial connecting lines when the load-side power converters include two half-bridges, or with four partial connecting lines when the load-side power converters includes three half-bridges. Each of the partial connecting lines has at least one semiconductor component for generating a voltage drop.
    Type: Grant

  • Publication number: 20180342945
    Abstract: A discharge device for discharging electrical energy from a circuit of an electrical converter includes an excitation device electrically connected to the circuit and producing during operation of the discharge device from the electrical energy of the circuit an alternating electromagnetic field, and an electrically conductive body constructed as a heatsink and receiving from the excitation device the alternating electromagnetic field so as to induce an eddy current in the electrically conductive body and converting the electrical energy generated in the electrically conductive body into thermal energy. Further disclosed is an electrical converter which includes the afore-described discharge device.
