Title: Controlling parallel inverter switching modules
Inventor: HART SIMON DAVID
IPC: H02M5/458
Filed: 2012-07-27
Abstract: A plurality of switching modules receive a DC electricity supply and generate an AC supply from the DC supply by the switching of the modules between conducting and non-conducting states. One or more characteristics associated with each of the switching modules is compared with an equivalent characteristic associated with one or more other of the multiple switching modules and a time period when the switch module is in the conducting state is controlled accordingly. The compared characteristic can be current, average current, accumulated current, temperature and/or indicative of a strain placed on the module. The conducting time period can be shortened by delaying the switch-on time when the parameter compared is greater than an average of the equivalent parameter. The parameter or characteristic can be determined by measurement or modelling. The inverter switching modules can be used for driving a load such as a motor.
