| 发明名称 | Power supply apparatus and driving method thereof | ||
| 摘要 | A power supply apparatus and a driving method thereof are disclosed. The power supply apparatus includes a first converter and a second converter. The first converter is operated to acquire a first gain when an input voltage is included in a first range or a second range that is lower than a first range and outputs a first output voltage and a second output voltage by converting the input voltage. In addition, the second converter is operated when the input voltage is included in the first range and outputs a third output voltage by converting the second output voltage. | ||

| 主权项 | 1. A power supply apparatus comprising: a first converter operated to acquire a first gain when an input voltage is included in a first range and configured to output a first output voltage and a second output voltage by converting the input voltage; and a second converter operated when the input voltage is included in the first range and configured to output a third output voltage by converting the second output voltage, wherein when the input voltage is included in a second range that is higher than the first range, the second converter is not operated and does not output the third output voltage. | ||
