Automatic compensation circuit for the horizontal deflection of a multifrequency computer monitor

摘要

An automatic compensation circuit for the horizontal deflection of a multifrequency computer monitor includes a transformer which has a primary winding and a secondary winding, a reverse coil which is reversely wired with respect to the secondary winding of the transformer being connected to the secondary winding of the transformer, a capacitor being serially connected between the reverse coil and a ground, a voltage/current converting circuit electrically connected to the first winding of the transformer, and a frequency/voltage converter being electrically connected between a computer monitor and the voltage/current converting circuit for converting the horizontal frequency of the computer monitor to a corresponding voltage and transmitting the converted voltage to the voltage/current circuit. The voltage/current converting circuit receives the converted voltage and responds to generate a corresponding current to actuate the transformer to generate a corresponding resonant frequency to compensate the horizontal deflection of the computer monitor.
