Abstract
A power supply circuit includes an energy storage element, a first switch, a voltage signal converter, a second switch, a third switch and a power supply. The first switch is coupled to the energy storage element at a first voltage output terminal. The voltage signal converter is coupled to, respectively, the energy storage element and the first switch at a first converter output terminal and a second converter output terminal. The second switch is coupled to the first switch. The third switch is coupled to the second switch at a second voltage output terminal. The power supply is coupled to the second switch and the third switch. The energy storage element, the first switch, the voltage signal converter, the second switch, the third switch and the power supply cooperate and generate a output voltage. A method of operating the power supply circuit is also disclosed herein.
