One trend that shows no size of ending is the move to smaller personal electronic devices. From smartphones to tablets, each successive generation is smaller and more powerful than the last. It’s ...

The quasi-resonant flyback (QRF) power converter is a popular choice in low-power offline applications in the 150-W-or-less output power range for many reasons. The QRF converter has a low component ...

The power lost in a dissipative clamp is related to energy stored in the leakage inductance of each switching cycle. When the FET is on, the current in the primary winding of the transformer increases ...

Sponsored by Texas Instruments: Adding gallium-nitride devices such as FETs to power-supply topologies such as the active-clamp flyback can lead to a variety of performance improvements. It’s not news ...
