COMMUNICATION IN A CONVERTER DEVICE

It is provided a method for synchronising time between a plurality of nodes of a converter device for high voltage power conversion. The method is performed in a first node of the converter device and comprises the steps of: receiving (40) a time reference from a second node; obtaining (42) a delay...

Zusammenfassung:	It is provided a method for synchronising time between a plurality of nodes of a converter device for high voltage power conversion. The method is performed in a first node of the converter device and comprises the steps of: receiving (40) a time reference from a second node; obtaining (42) a delay value for receiving time references from the second node; determining (44) a compensated time by adding the delay value to the time reference; and setting (46) a clock in the first node to be the compensated time.
