摘要： A regulated power supply having power factor correction control includes a multi-vector error amplifier. The multi-vector error amplifier provides an error signal that is used to regulate a switching mechanism of the power supply. The multi-vector error amplifier acts to provide a low distortion error signal during steady-state operation, while responding rapidly and smoothly to sudden load changes.

摘要： A power supply comprises an input voltage detector that detects a drop in input voltage that corresponds to an input voltage loss. A power converter is coupled to the input voltage detector. The power converter, which may be a boost converter or a power factor correction converter, has a switching device that is actuated in accordance with a duty cycle. A duty cycle adjuster is responsive to detection of the drop in the input voltage to adjust the duty cycle of the switching device in order to limit an input current surge through the switching device below a desired level after the input voltage returns.

摘要： A PWM controller according to the present invention provides a technique to control the output voltage and output current of the power supply without the feedback control circuit in the secondary side of the transformer. In order to achieve better regulation, an adaptive load and a feedback synthesizer are equipped into the PWM controller, which associated with the auxiliary winding of the transformer regulate the output voltage of the power supply as a constant. Furthermore, a programmable power limiter in the PWM controller controls the power that is delivered from the primary side to the output of the power supply. The threshold of the power limit is varied in accordance with the change of output voltage. Because the output power is the function of the output voltage of the power supply, a constant current output is realized when the output current of the power supply is greater than a maximum value.
