ABSTRACT:
In a paralleled inverter system, a positive feedback current derived from the total current from all of the modules of the inverter system is applied to the base drive of each of the power transistors of all modules, thereby to provide all modules protection against open or short circuit faults occuring in any of the modules, and force more equal current sharing among the modules during turn-on of the power transistors.
