Method and circuit for detecting input voltage of power converter |
摘要 |
The present invention provides a method and circuit for detecting an input voltage of a power converter. It includes a current sense circuit for generating a current signal in response to a switching current of an inductive device. A detection circuit is coupled to sense the current signal for generating a slope signal in response to a slope of the current signal. A signal generation circuit is further developed to generate an input-voltage signal in accordance with the slope signal. The level of the input-voltage signal is corrected to the input voltage of the power converter.
