Abstract
Disclosed are implementations that include a non-isolated power converter system comprising a filter including an inductor and a capacitor. The inductor of the filter includes a core portion and a winding portion. The core portion may include different shape core structures. The winding portion includes a winding embedded within a printed circuit board. The printed circuit board winding may include a litz wiring, and the printed circuit board having located thereon one or more of a controller or power switching elements.
Claims22
-18. (canceled)
An inductor for a filter in a power converter system, the inductor comprising:
- a core portion;
- and
- a winding portion that forms an inductor with the core portion, the winding portion including a winding embedded in a printed circuit board and having a first terminal and a second terminal, the winding embedded in the printed circuit board forming a litz PCB in which the winding includes multiple layers of parallel strands routed in the printed circuit board.
-59. (canceled)
A power converter system, the system comprising:
- a power converter including power switching elements;
- a controller configured to drive the power switching elements to convert received power and to output converted power;
- and
- a filter including an inductor and a capacitor, the filter coupled to the power converter, wherein the inductor includes:
- a core portion;
- and
- a winding portion that forms an inductor with the core portion, the winding portion including a winding embedded in a printed circuit board and having a first terminal and a second terminal, the winding embedded in the printed circuit board forming a litz PCB in which the winding includes multiple layers of parallel strands routed in the printed circuit board.
A method of power conversion, the method comprising:
- receiving, by a power converter including power switching elements, input power;
- driving, by a controller, the power switching elements to convert received input power to output converted power;
- and
- filtering, by an LC filter including an inductor and a capacitor that is coupled to a first side of the power converter, a power signal on the first side of the power converter,
- wherein the inductor includes a core portion and a winding portion, wherein the winding portion includes a winding embedded in a printed circuit board,
- wherein the winding embedded in the printed circuit board forms a litz PCB in which the winding includes multiple layers of parallel strands routed in the printed circuit board.
