摘要： In a horizontal deflection and high voltage generating circuit in a television receiver, the high voltage is regulated to remain substantially constant with variations in picture tube beam current variation and receiver direct current power supply variation. A high voltage variation representative signal is coupled to a regulator circuit including a saturable reactor magnetically biased such that a failure comprising either a short or open circuit in the regulator circuit causes the input energy to the deflection circuit not to increase beyond a predetermined amount.
