Abstract :
A new commutation method for a full-bridge current-source inverter is presented. Three intermediate steps are inserted during the commutation to provide conducting paths for the load current. The step change of the load current and the resulting voltage spike are reduced. Experimental results which conform to the theoretical analysis are presented.
