20. A method for providing a power supply by a power converter, the power converter comprising a DC/DC converting circuit and a first energy storage element serially connected to the output terminal of the DC/DC converting circuit, comprising:
-
providing a variable electric power through the DC/DC converting circuit; providing a switch, of which the first connecting terminal and the third connecting terminal is electrically connected, thereby allowing the DC/DC converting circuit solely to provide the power supply to the external load; detecting the voltage across the external load; and when the voltage across the external load is equal to or greater than a predetermined voltage, the third connecting terminal of the switch is switched to electrically connect with the second connecting terminal, thereby allowing the DC/DC converting circuit together with the first energy storage element to provide the power supply to the external load. - View Dependent Claims (21)
