Abstract
A power supply for a microwave magnetron includes a transformer having a secondary winding, a capacitor connected to one end of the winding, a magnetron connected in between the remaining end of the capacitor and the winding so as to form a first unidirectional current conducting path capable of conducting current in one direction and a second circuit connected in shunt of the magnetron having unidirectional current conduction characteristics and being switchable to an On or Off condition, said second circuit being electrically poled opposite to the polarity of the magnetron and means for controlling the switching of the second circuit to its current conducting condition as a function of the magnitude of current through the magnetron.
