Patent number: 9762116Abstract: 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, 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.Type: GrantFiled: February 11, 2016Date of Patent: September 12, 2017Assignee: OMRON AUTOMOTIVE ELECTRONICS CO., LTD.Inventors: Takashi Yamaguchi, Akihiro Kinoshita, Shinji Horio
