Multiphase voltage regulator having coupled inductors with reduced winding resistance
(United States Patent and Trademark Office, 2007-04-03)
A multiple phase buck converter or boost converter, or buck-boost converter has an inductor in each phase. A magnetic core with a unique woven topology provides inverse coupling between the inductors. The inductors can ...
Current sensing in multiple coupled inductors by time constant matching to leakage inductance
(United States Patent and Trademark Office, 2007-06-19)
Voltage regulators often have coupled output inductors because coupled output inductors provide improvements in cost and efficiency. Coupled inductors are often used in multi-phase voltage regulators. Feedback control of ...
