ABSTRACT:
A method for converting an input voltage signal into an output voltage signal is disclosed. The method includes: providing a primary converting module and coupling the primary converting module to an input port of the voltage converter; providing a secondary converting module having a second electronic induction device and a switch device, coupling the secondary converting module to an output port of the voltage converter, and utilizing the switch device to enable the secondary converting module; measuring a slope of an output at a detection end of the second electronic induction device to generate a slope indication signal having different pulse amplitudes representative of different slope values; and referencing the output at the detection end of the second electronic induction device, the slope indication signal, a first predetermined reference level, and a second predetermined reference level to generate a control signal for controlling an on/off status of the switch device.
