Abstract
The present invention is a method and system for preventing voltage spike feedback with switched inductive loads connected to isolated redundant power supplies. A voltage clamp circuit of the present invention may clamp the voltage spikes caused by inductive loads within a power supply system to a safe voltage level. When the common output voltage of the redundant power supplies becomes too large, the voltage clamp circuit of the present invention may clamp the common output voltage to a safe voltage level at or slightly above the higher voltage of the parallel connected power supplies.
