摘要： A flyback transformer (FBT) driving apparatus for video display appliances which can prevent deterioration of the FBT efficiency caused by excessive horizontal frequency input. The FBT driving apparatus employs a PWM-type circuit to evenly maintain the Vcc power supply provided to the primary winding of the FBT irrespective of the excessive horizontal frequency input. The FBT driving apparatus makes use of the horizontal frequency per se in the low frequency band, while dividing the horizontal frequency by a half in the high frequency band to enable operation of the FBT by means of ordinary rectifying diodes even in the input of the high horizontal frequency and to prevent deterioration of the FBT efficiency caused by input of the high horizontal frequency.
