A high speed control network synchronization jitter evaluation for embedded monitoring and control in modular multilevel converter

A high speed ring control network is highly demanded to simplify the wiring system in a complex Modular Multilevel Converter (MMC). However, the propagation delay introduced in the ring system must be compensated. The ideal synchronization jitter for power switches to turn on or turn off simultaneously is set as ±20 ns. This paper will evaluate the synchronization jitter of a potential control network (EtherCAT) experimentally. Full analysis result will be presented.
