Abstract
Official abstract text for this publication.
A voltage conversion apparatus includes a booster circuit, a boost stop circuit, a Zener diode, and a capacitor. The boost stop circuit includes a transistor. When an overvoltage equal to or larger than a breakdown voltage of the Zener diode is output to an output line of the booster circuit 11 , the Zener diode is turned on. Accordingly, the transistor is turned on and a switching element is turned off to stop a boost operation. Further, the capacitor is charged through the Zener diode. Even when the Zener diode is turned off due to a drop in the output voltage after the stop of the boost operation, the transistor maintains its on state for a certain time by discharge of the capacitor. Thus, the stop of the boost operation is continued.
First claim
Opening claim text (preview).
1 . A voltage conversion apparatus comprising: a booster circuit comprising a switching element, the booster circuit configured to boost an input voltage by turning on and off the switching element; a Zener diode having a cathode connected to an output line of the booster circuit; a capacitor connected between an anode of the Zener diode and a ground; and a boost stop circuit configured to turn off the switching element to stop a boost operation in response to turning on of the Zener diod…
