<p>PROBLEM TO BE SOLVED: To provide a power supply unit and a load driving method, capable of rapidly lowering electric power stored by a capacitor.SOLUTION: Electric power is supplied from a first capacitor 23 to a high power device 28 and an electrical apparatus 29 through a DC-DC converter 21. A voltage detector 30 detects an output voltage of the first capacitor 23. A controller 31 determines whether or not an output voltage detected by the voltage detector 30 is at least a threshold voltage. The controller 31, when it is determined that the output voltage is at least the threshold value, drives a cooler 27 or a high power device 28.</p> |
