<p><P>PROBLEM TO BE SOLVED: To provide a small-capacity power supply for receiving supply of alternating-current voltage and outputting low alternating-current voltage that is small-sized, lightweight, excellent in voltage conversion efficiency, and of low cost. <P>SOLUTION: When an alternating-current voltage of 100V is applied to between the connecting terminals 1, 2 for alternating-current voltage of the small-capacity power supply, the following takes place. The alternating-current voltage is divided through a first capacitor 5 and a second capacitor 9, and any excessive voltage is limited by a voltage limiting element 8. Then, it is outputted to between output terminals 3, 4. Since a fixed resistor is used for limiting a rush current in place of a reactor, a cost can be reduced and thus size reduction can be achieved. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
