| 20110227546 | DC-DC CONVERTER - To eliminate the problem that a magnetic deflection is caused in a transformer even when a coupled inductor converter is in a stationary operation state, provided is a DC-DC converter including a first series circuit portion formed by a first switching transistor, a first capacitor, a first inductor, and a second capacitor which are connected to a DC power in series in this order, and a second series circuit portion formed by a second switching transistor and a second inductor which are connected in series in this order, the second series circuit portion is connected in parallel to the first capacitor and the first inductor, and the first inductor and the second inductor constitute a coupled inductor having a plurality of windings and a common magnetic core. | 09-22-2011 |
