摘要：An ultra voltage representative signal is applied to the input of a disabling latch circuit of a television receiver high voltage protection circuit. Two diodes are coupled across the inductive portion of an oscillator tank network, with the cathodes of the two diodes coupled at a junction in common with the output terminal of the disabling latch. If the ultra voltage exceeds a predetemined level, the latch is energised forward biasing both diodes to provide a short-cricuit across the tank network. Sustained output signal is removed to disable operation of the high voltage generator.
