  • 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
