ABSTRACT:
A regulated DC voltage power supply including a plurality of power circuits connected in parallel, and a control circuit. Each of the power circuits includes a switching device that chops the input DC voltage, and the control circuit includes a detecting circuit, a control IC, and a timing adjusting circuit. The ripple components of the output voltage produced as the output of the parallely connected power circuits is less than the ripple components of individual power circuits. This makes it possible to realize a small, high efficiency regulated DC voltage power supply with low rated current semiconductor switching devices.
