BOOSTED COUPLED INDUCTORS AND ASSOCIATED SYSTEMS AND METHODS

A switching power converter includes a first switching stage, a second switching stage, a coupled inductor, and a boost winding. The coupled inductor includes a first phase winding, a second phase winding, and a magnetic core. The first phase winding is wound at least partially around a first portion of the magnetic core, and the first phase winding is electrically coupled to the first switching stage. The second phase winding is wound at least partially around a second portion of the magnetic core, and the second phase winding is electrically coupled to the second switching stage. The boost winding forms at least one turn such that mutual magnetic flux associated with each of the first and second phase windings flows through the at least one turn. 一种开关电源转换器包括第一开关级、第二开关级、耦合电感器和升压绕组。该耦合电感器包括第一相绕组、第二相绕组和磁芯。该第一相绕组至少部分地缠绕在该磁芯的第一部分上，并且该第一相绕组电耦合到该第一开关级。该第二相绕组至少部分地缠绕在该磁芯的第二部分上，并且该第二相绕组电耦合到该第二开关级。该升压绕组形成至少一匝，使得与该第一相绕组和该第二相绕组中的每一个相关联的互感磁通流过该至少一匝。
