For the PDF version of this article, click here. The leakage inductance of the power transformer of an isolated dc-dc converter may significantly affect its efficiency and cost. Using lossless ...

In the standard form of a flyback converter, the leakage inductance of the transformer creates a voltage spike on the drain of the primary field-effect transistor (FET). Preventing this spike from ...

With the ever-growing demand of electronic devices to do more processing in a smaller package, the top priority on any power supply these days is power density. The most popular isolated power supply ...

Power Integrations has moved to active clamp fly-back conversion, zero voltage switching and a GaN transistor to shrink the size of its ac-dc USB-C charger circuits. The chips implementing the ...

The active clamp transformer reset technique offers many well-documented advantages over traditional single-ended reset techniques, including lower voltage stress on the main MOSFET, the ability to ...
