Beschreibung
Zusammenfassung:	An improved boost converter is electrically connected between a power source and a load so as to allow the voltage applied to the load to be higher than the voltage supplied by the power source. The improved boost converter comprises a KY boost circuit, an input capacitor and an input inductor. The effect of the present invention is: only two additional passive elements are required in the KY boost circuit. The input voltage is raised by charging the input capacitor through the input inductor, such that the boost ratio of the improved boost converter in the present invention is higher compared to the original KY boost circuit. Not only the input current ripple can be lowered by the input inductor but also the output voltage ripple can be reduced by cooperating with the output inductor of the KY boost circuit.
