  • COMMUNICATION IN A CONVERTER DEVICE
    Publication number: 20230095300
    Abstract: A method can be used to synchronize time between nodes of a converter device for high voltage power conversion. The method is performed in a first node of the converter device and includes receiving a time reference from a second node of the converter device, obtaining a delay value for receiving time references from the second node, determining a compensated time by adding the delay value to the time reference, and setting a clock in the first node to be the compensated time.
    Type: Application

  • Cooling system for an electrical machine
    Patent number: 8581456
    Abstract: A cooling system for an electrical machine includes a substantially closed housing, a first heat exchanger arranged inside of the housing, a second heat exchanger arranged outside of the housing, a conduit assembly for transferring a heat exchange medium in a closed circuit between the first and the second heat exchangers, a first air circulating means configured to circulate air inside of the housing over the first heat exchanger, and a second air circulating means configured to circulate air outside of the housing over the second heat exchanger, wherein the conduit assembly includes a pump for actively circulating the heat exchange medium between the first and the second heat exchangers.
