ABSTRACT:
The present disclosure relates to a power supplier for a magnetron for use in electric appliances, such as a microwave oven. The power supplier of the present disclosure has a solid state frequency converter which changes commercial A.C. power to A.C. power at a high frequency, which A.C. power is increased in voltage in a step-up transformer and then fed to the magnetron. The power supplier further has a control system which stabilizes the power to be applied to the magnetron with respect to a preselected reference level and a power supplier protecting circuit for protecting the power supplier from an unexpected low voltage occurring in the commercial power source.
