He’s using a flyback transformer with a zero voltage switching (ZVS) driver. This produces about 50 kV, which is more than enough to toast the marshmallow.

Although we've ignored the transformer action, as it's not a design parameter, it still exists. The flyback voltage is reflected back to the primary winding during the OFF period of Q1.

The flyback transformer isn’t just a simple turns-ratio magnetic component, so the datasheet explains in detail how to determine its specifics and size it for the voltage, current, and power ...

Designing flyback transformers for switch-mode power supplies involves many calculations. A spreadsheet can make short work of this otherwise-tedious task. When you develop flyback power supplies, ...

A single-stage-transformer-flyback topology operates from ac-line voltage but has a different switching control that directly gives an isolated low-voltage output at a high power-factor figure (Figure ...

My annoyance then every time I see a self oscillating converter using a flyback transformer is this: why can’t they use a flyback circuit, all they have to do is find a TV service manual or two ...

Because of these drawbacks, a second converter, typically a flyback transformer, provides isolation from this high dc voltage, allows a safety ground reference, and provides a regulated lower output ...

The flyback transformers tend to hold a charge, similar to that of a leyden jar. Its always a good idea and safety precaution to discharge them, even though its unlikely to be a lethal shock.

The HM210-05K060LFTR flyback transformer from TT Electronics is designed for use with Avago's ACPL-32JT/302J IGBT chipset. With its high level of isolation, the transformer is said to be optimised for ...

Experimenting with flyback transformers element14 and Bourns launched the Experimenting with Flyback Transformers Design Challenge. The competition invites design engineers and enthusiasts to explore ...
