Abstract
A DC/DC converter (100) includes a voltage conversion unit (20) having an input node to receive an input voltage and an output node to output an output voltage and configured to convert the input voltage to the output voltage to output the output voltage from the output node, and an electrical energy storage unit (GC2) including a first electrode to be a positive electrode and a second electrode to be a negative electrode. The first electrode is electrically connected to the input node of the voltage conversion converter. The DC/DC converter (100) further includes a switching unit (S1) configured to electrically connect the second electrode of the electrical energy storage unit to one of ground and the output node of the voltage conversion unit alternatively. The switching unit (S1) connects the second electrode of the electrical storage unit (GC2) to the output node when the input voltage is lower than a predetermined voltage.
