Title: Magnetron power supply
Inventor: ITO ATSUSHI
IPC: H02H11/00
Filed: 1989-03-31
Abstract: PURPOSE:To increase safety of a magnetron power supply by constituting the magnetron power supply in such a manner as to detect the resistance value of the filament of a magnetron and prohibit the outputs of a filament power supply and an anode high voltage power supply when the detected resistance value deviates from a predetermined fixed range. CONSTITUTION:From a filament resistance value measuring constant voltage power supply 110, a constant voltage of V1 is applied to a filament 13 through a diode D1 and a filament current measuring resistance R. When the current value at that time is I1, a potential difference of rXI1 [V] is generated on the both ends of the filament current measuring resistance R. When the filament 13 is abnormal, the above rXI1 [V] deviates from a range predetermined in a window comparator IC1, a filament resistance abnormality signal is outputted to make the coil of a filament resistance normal detecting relay R2 in non- excited state. Consequently, the contact point of a power supply feed relay R1 is opened to stop power supply feed to an anode high voltage power supply 10 and a filament DC power supply 20.
