  • Publication number: 20240055993
    Abstract: A converter comprises a first circuit part and a second circuit part configured to be electrically connected with each other. Each circuit part comprises two or more switches configured to be switched for the power conversion, the switches being semiconductor switches. The two or more switches of the first circuit part are configured for a first switching operation of the first circuit part. The two or more switches of the second circuit part are configured for a second switching operation of the second circuit part. The first switching operation causes a greater electrical power loss compared to the second switching operation. The two circuit parts are configured such that the first circuit part is configured to operate at a higher operating temperature compared to the second circuit part.

  • Patent number: 11791741
    Abstract: A power converter assembly includes a semi-conductor module, a heat sink mechanically connected to the semi-conductor module, a first busbar assembly on a first side of the heat sink, and a second busbar assembly on a second side of the heat sink opposite from the first side. The first and second busbar assemblies are electrically connected to one another. A power converter assembly includes a plurality of sets of semi-conductor modules, a common heat sink mechanically connected to each semi-conductor module, a first busbar assembly on a first side of the common heat sink, and a second busbar assembly on a second side of the common heat sink opposite from the first side. The first and second busbar assemblies are electrically connected to one another.

  • Patent number: 11482854
    Abstract: There is disclosed a circuit breaker arrangement for interrupting a current flowing through a direct current (DC) transmission line including a semiconductor switching device and a pulse injection circuit configured to inductively inject into the transmission line a pulse current that opposes the current flowing through the transmission line to thereby reduce the current in the transmission line to cause the semiconductor switching device to turn-off to interrupt the path for the current flow through the transmission line.

  • Patent number: 10291111
    Abstract: A system and method includes parallel power converters, at least one current sensor, and a first feedback control circuit. A first power converter is configured to convert a first input power to a first output power, and is controlled using pulse width modulation having a first switching period. One or more second power converters are connected in parallel with the first power converter and configured to convert a second input power to a second output power. The first output power and the second output power are provided to a load. The at least one current sensor is positioned to sense first output current of the first output power, and the first feedback control circuit is configured to calculate a first metric based on the first sensed current at each of a plurality of first edges of each half switching period of the first switching period, and at intermediate points between each of the plurality of first edges.
