Photoflash and strobe devices operate by discharging a high voltage capacitor into a bulb. Operation of these circuits from a battery or other low-voltage source requires a step-up dcdc converter to ...

Download this article in PDF format. If you search the internet for “transformer equivalent circuits,” you’ll get five pages of over 100 small circuit diagrams. Figures 1 and 2 show two typical ...

In recent electronic devices, the demand for energy savings has become increasingly difficult to meet due to very stringent requirements such as high efficiency, low power dissipation, and reduced ...

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.
