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 ...

Which topology do you chose when your specification calls for a non-isolated power supply and the output voltage falls between the minimum and maximum input voltage? Is the tried-and-true flyback used ...

The low-power (milliwatt) flyback transformer used in a switched-mode power supply (SMPS) needs to be designed with a gap in the magnetic path for maximum power delivery over temperature. Transformers ...

China is emerging as a large manufacturer of CRT-based TV components, says Daniel Yang in iSuppli’s "Market Watch—China," (March 31, 2003, Vol. 2). He notes that the rapid growth of China’s color TV ...

When developing TOPSwitch flyback power supplies, transformer design is usually the biggest stumbling block. Flyback transformers are not designed or used like normal transformers. Energy is stored in ...

Everyone likes to play with high voltages, right?. Even though the danger of death goes up with every volt, it’s likely that a few readers will have at some time or other made fancy long sparks.

In this article, I'll show you how to build a simplistic circuit to generate negative ions. Negative ions have been known to contribute to fresher air, happier mood, and general health benefits.
