Asymmetrical coupled inductors and associated methods |
摘要 |
An asymmetrical coupled inductor includes a first and a second winding and a core. The core is formed of a magnetic material and magnetically couples together the windings. The core is configured such that a leakage inductance value of the first winding is greater than a leakage inductance value of the second winding. The coupled inductor is included, for example, in a multi-phase DC-to-DC converter. A DC-to-DC converter including a symmetrical coupled inductor includes at least one additional inductor electrically coupled in series with one or more of the coupled inductor's windings. A controller for a DC-to-DC converter including a first phase having an effective inductance value greater than an effective inductance value of a second phase is configured to shut down the second phase while the first phase remains operational during a light load operating condition. |
