Abstract
A system for optimizing dead time of switches, for example in power converters, using software. The system is first calibrated. The system determines the state that switches should be in. If the switch state needs to be changed, the system determines an optimized dead time which needs to be waited between turning one switch off and a complimentary switch on. The system controls the switches to turn on or off switches and waiting only the duration of the optimized dead time.
