摘要：A demagnetization circuit that is used in a push-pull circuit, when the positive-half-period circuit is on and the negative-half-period circuit is off, a pulse widthmodulation signal (Vga) at MOSFET side of the positive-half-period circuit is inversed

(PWB) and then transmitted into negative-half-period demagnetization circuit, whichrenders the negative-half-period demagnetization circuit conducted and short so thatthe demagnetization is operated during the positive-half-period; when the negative-half-period circuit is operating, a pulse width modulation signal (Vgb) at MOSFET side of thenegative-half-period circuit is inversed (PWB) and then transmitted into positive-half-period demagnetization circuit, and the above circuits are alternatively switched andshort for demagnetization so as to prevent the transformer from generating remanentmagnetization.
