1. realize a method for the primary control of constant output current, it is characterized in that, it can maintain inverse excitation type converter constant output current, and it comprises:

  • A) inverse excitation type converter is used to assist the voltage at winding two ends to produce feedback signal;

    B) object time is determined by the charge number compared on timer capacitor;

    C) delay between object time and feedback signal trailing edge is used to obtain error signal;

    WithD) output voltage of use error signal adjustment pulse-width modulation error amplifier.
