Abstract
There is provided a power supply, including, a boost converter unit including a first boost converter having a first inductor, a first diode, and a first switching element, and a second boost converter having a second inductor, a second diode and a second switching element, an input voltage sensing unit sensing an input voltage applied to the boost converter unit, a control unit selecting one of a first boost mode in which current is divided between the first inductor and the second inductor, based on the input voltage, and a second boost mode in which current flows through the first inductor and the second inductor in this order, based on the input voltage, and a switching unit selecting one of the first boost mode and the second boost mode, based on the selection of the control unit.
