Abstract
A power converter may comprise a magnetic core, a transformer primary winding configured to generate a magnetic field in the magnetic core, and a transformer secondary winding matrix. The transformer secondary winding matrix may comprise a plurality of secondary windings configurable between various electrical connections relative to one another (e.g., in series or in parallel) to adjust a voltage conversion ratio of the power converter.
Claims21
A power converter, comprising:
- a transformer primary winding;
- and
- a transformer secondary winding and switching matrix, comprising:
- a plurality (n) of secondary windings;
- and
- a plurality (n−1)*3 of switches,
- wherein the plurality of switches are configurable between open and closed positions to configure the plurality of secondary windings between series and parallel positions relative to each other to vary a voltage ratio of the power converter.
A power converter, comprising:
- a magnetic core;
- a transformer primary winding configured to generate a magnetic field in the magnetic core;
- and
- a transformer secondary winding matrix, comprising:
- a first winding having a first number of turns;
- and
- a second winding having a second number of turns,
- wherein the first winding and the second winding are configured to transform the magnetic field in the magnetic core into an electric power, and
- wherein the first winding comprises a first surface contact and a second surface contact, and
- the second winding comprises a third surface contact and a fourth surface contact,
- wherein the first surface contact, the second surface contact, the third surface contact, and the fourth surface contact are disposed on a board edge connector, and a configuration card is configured to connect to the board edge connector, wherein a voltage ratio of the power converter is configured in response to the configuration card being connected to the board edge connector.
15-16. (canceled)
The power converter of claim 16, wherein the configuration card comprises a plurality of connectors disposed on the configuration card, wherein the plurality of connectors contact at least one of the first surface contact, the second surface contact, the third surface contact, or the fourth surface contact in response to the configuration card being connected to the board edge connector.
A method for configuring a voltage conversion ratio of a transformer, comprising:
- connecting a first connector to a first winding of a transformer secondary winding matrix;
- connecting a second connector to a second winding of the transformer secondary winding matrix;
- wherein the first winding and the second winding surround a magnetic core,
- the first connector is configured to receive an electric current from the first winding,
- the first connector is connected to the first winding in response to a configuration card being connected to a board edge connection of the transformer, wherein the first connector is disposed on the configuration card, and
- the second connector is connected to the second winding in response to the configuration card being connected to the board edge connection of the transformer, wherein the second connector is disposed on the configuration card.
