Crowbar (circuit) A crowbar circuit is an electrical circuit used for preventing an overvoltage condition of a power supply unit from damaging the circuits attached to the power supply. It operates by putting a short circuit or low resistance path across the voltage output (V o ), quite like were one to drop a crowbar across the output terminals of the power supply. Short Circuit Protection Circuit Diagram Short circuit is unintended connection between two terminals which are supplying power to the load.It can happen both in AC or DC circuit, if it is an AC supply then short circuit can trip the power supply of whole area, but there are fuses and overload protection circuits at many levels, from the power station to the house.
