ABSTRACT:
A method and apparatus for detecting system failure in a magnetron power supply circuit. The apparatus is capable of providing an indication as to whether it is the power supply or the magnetron which has failed. A dual half wave doubler power supply circuit is provided and the currents corresponding to the respective dual portions are measured. The currents are compared to detect a failure of one of the dual power supply circuits while a sum of the currents may detect a failure of the magnetron.
