High voltage stabilizing circuit for preventing overheat

A high voltage stabilizing apparatus comprising:

• horizontal synchronization drive means for developing a drive signal in response to a horizontal synchronization signal input thereto;
• horizontal synchronization output means for developing a pulse signal in response to said drive signal;
• frequency converting means for developing first and second input signals in response to said horizontal synchronization signal;
• a first comparator for developing a first comparison signal responsive to said first input signal and a first reference signal input thereto;
• a second comparator for developing a second comparison signal responsive to said second input signal and a second reference signal input thereto;
• third power control means for developing a third control output signal in response to said first comparison signal and a third power supply input thereto;
• second power control means for developing a second control output signal in response to said third control output signal, a second power supply and said second comparison signal input thereto;
• first power control means for developing a first control output signal in response to said second control output signal and a first power supply input thereto;
• flyback transforming means having a primary coil and a secondary coil for developing a high voltage output signal in response to said first control output signal being connected to a first node of said primary coil and said drive signal being connected to a second node of said primary coil;
• and
• amplifying means being connected to said secondary coil for developing an amplified control signal to said first power control means, said first, second, and third power supplies being applied to said flyback transforming means in response to said horizontal synchronization signal.
