ABSTRACT:
A power processor having a switching type output is provided with protection against short circuit current flow. A transformer is provided with the primary windings connected in series with the main current flow path. The secondary transformer windings have a voltage signal induced therein which is indicative of a rapidly rising short circuit current flow. A threshold detector connected to the output from the secondary windings determines when the voltage signal from the secondary windings exceeds a predetermined value. The signal from the threshold detector is used to activate over current protection circuitry which shuts down the output switching devices and prevents the occurrence of large short circuit currents.
