Magnetic element in a non-saturated region in a trnsformer/ inductor

A transformer comprising:

• a core;
• a primary winding wrapped around the core;
• at least one secondary winding wrapped around the core;
• and
• wherein the core comprises at least one magnetic element operating in a non-saturated region (NSME).

A transformer comprising:

• a primary winding surrounding a plurality of core elements;
• a secondary winding wrapped around a member of the plurality of core elements;
• and
• wherein at least one core element comprises a magnetic element operating in a non-saturated region (NSME).

In a power conversion circuit having an energized magnetic element, the improvement comprising:

• said magnetic element operating in a non saturating region (NSME) thereof;
• said magnetic element having a natural frequency;
• and
• said energizing power approximately matched to said natural frequency thereby providing a higher power density, an improved thermal stability, and an increased conversion efficiency.

An inductor comprising:

• a core;
• a winding;
• and
• wherein the core has a magnetic element operating in a non-saturated region (NSME).

An inductor comprising:

• a plurality of cores;
• a winding around at least one member N of the plurality of cores;
• and
• wherein the member N has a magnetic element operating in a non-saturated region (NSME).
