Abstract: 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.

Abstract translation: 电压转换装置包括升压电路，升压停止电路，齐纳二极管和电容器。 升压停止电路包括晶体管。 当等于或大于齐纳二极管的击穿电压的过电压被输出到升压电路11的输出线时，齐纳二极管导通。 因此，晶体管导通，并且开关元件被断开以停止升压操作。 此外，电容器通过齐纳二极管充电。 即使由于在升压操作停止之后输出电压下降而使齐纳二极管截止，晶体管通过电容器放电而保持其导通状态一段时间。 因此，继续进行升压动作的停止。

Abstract: A DC-DC converter includes a voltage conversion circuit boosting a voltage of a DC power supply and supplying the voltage to a load, a bypass circuit provided in parallel to the voltage conversion circuit, a drive circuit turning on and off a switching element of the bypass circuit, and a controller outputting a control signal for controlling the voltage conversion circuit and the drive circuit. A diode is connected in parallel to the switching element so as to be oriented toward a forward direction with respect to the DC power supply. A temperature detector of the drive circuit detects temperature of the diode. The drive circuit maintains the switching element in the on state irrespective of the control signal of the controller when the temperature detector detects a temperature greater than or equal to a predetermined value.

Abstract: The present invention provides a power-supply device, which can continuously supply a voltage from a power supply to a load even if a breakdown of a circuit is generated. The power-supply device includes a booster circuit, a normally-closed bypass relay, a CPU, and a switching circuit. A first switch of the switching circuit is turned on by a switching signal from the CPU, and a second switch is turned on by a boosting request signal from a boosting request signal generator. In the case that one of or both the switching signal and the boosting request signal are not input to the switching circuit 14, because a coil of a bypass relay is not energized, a contact turns on, and a voltage is supplied from a DC power supply to the load through the contact. When both the switching signal and the boosting request signal are input to the switching circuit, the coil is energized to turn off the contact, and a voltage supply path to the load is switched from the side of the bypass relay to the side of the booster circuit.
