  • Flyback converter system and feedback controlling apparatus and method for the same
    Patent number: 8804379
    Abstract: A flyback converter system and feedback controlling apparatus and method of operating the same are disclosed. The feedback controlling apparatus for the flyback converter system includes a primary feedback loop unit for generating a primary feedback signal, and a secondary feedback loop unit for generating a secondary feedback signal, a loop selector. In light-load conditions, the loop selector supplies the primary feedback signal to a PWM controller for feedback control, and the secondary feedback loop unit is disabled by a power monitor to save electrical energy.
