Abstract: A voltage conversion apparatus includes a power supply circuit with a first switch, a voltage conversion circuit, and a protective circuit with a detection circuit. The first switch transmits a power to generate an input voltage. The voltage conversion circuit generates a first voltage. A second switch of the voltage conversion circuit receives the input voltage. A third switch of the voltage conversion circuit is coupled between the second switch and a ground terminal.
