ABSTRACT:
A resonant mode power supply includes a d.c. voltage source and switching elements for alternatively connecting an oscillating circuit, including the primary winding of a transformer, to the d.c. voltage source and to ground. In order to detect faults in the load on a secondary side of the transformer which would cause the resonant mode power supply to attempt to supply and inordinate amount of power, the power on the primary side is detected and if this primary power exceeds a predetermined threshold value, the frequency of oscillation is increased to reduce the power. If the fault condition persists, the switching of the switching elements is discontinued.
