A common part used to create a high voltage is a CRT flyback transformer, having been a ubiquitous junk pile component. So many attempts to use them rely on brute force, with power transistors in ...

With the LT6813, designers can build an optoisolator-free power controller that delivers from 20- to 600-V dc output up to 100 W using an updated version of the long-established “flyback” principle.

In this article, I'll show you how to built a Wireless Transfer of Energy Transmitter. Simply put, this device will send electricity to a florescent light bulb and light it up, from up to three feet.
