Abstract: A rectifier circuit includes: a switching circuit having an input end, an output terminal and a control end, wherein the input end of the switching circuit receives an input voltage; a control circuit electrically connected to the control end of the switching circuit, wherein, when a load current is smaller than a reference current, the rectifier circuit is situated at a light-load state and the control circuit reduces a switching frequency of the switching circuit; and a filtering circuit which is electrically connected between the output end of the switching circuit and an output terminal of the rectifier circuit, and includes at least one inductive component of which a current is formed by superposition of the load current and a ripple current, wherein, when the load current is smaller than the reference current, an inductance of the inductive component increases with the decrease of the load current.

Abstract: A computer-assisted schematic linking method for electronic components includes naming the circuits of various electronic components according to signal line naming conventions; storing in an electronic component specification data base; selecting a plurality of first electronic components from the electronic component data base to generate a first electronic component list for users to select the first electronic components; searching second electronic components from the electronic component data base corresponding to the selected first electronic components and generating a second electronic component list for users to select the second electronic components; processing schematic linking operation for the first electronic components and the second electronic components; and repeating the foregoing steps to select other electronic components until a complete schematic chart is finished.
