PURPOSE:To attain an action stop even when abnormal high voltage is generated in a correcting transformer by providing a coil for detecting abnormal high voltage/high voltage on the correcting transformer and adding required voltage including the coil for the detecting abnormal high voltage of a main transformer to a Zener diode for stopping high voltage. CONSTITUTION:The output end of a first rectifying circuit 2 to rectify voltage generated in a coil for detecting high voltage 4 of a main transformer 1 is connected to the one end of a coil for detecting high voltage 7 and the other end of the coil 7 is connected to a Zener diode for stopping high voltage 23 through a second rectifying circuit 22. Then, the both-end voltage of the coil 4 and the both-end voltage of the coil 7 affect to the both-end voltage of the diode 23 together and even when abnormal high voltage is generated in any coil for detecting high voltage, the Zener diode can be broken down. |
