Abstract

A controller for combined parallel- and series-connected IGBT modules is reported. An advanced system state classification is applied to allow for real-time reconfiguration of the local controller structure. Thereby, a new scheme for controlling the rate of increase of the collector current is introduced. A globally synchronous sampling time for synchronizing multiple modules is derived locally. This avoids the need of high timing resolution in the optical links
