Inductors range from RF coils used in communications through switchmode inductors used in power supplies and differential and common mode inductors in EMI filters. As switchmode power supply designs ...

The 555 multivibrator circuit has become a default choice of many hobbyists and even professionals in the past 50 years. Its pair of equations for frequency and duty cycle easily gives ...

Previous tutorials have shown the properties and characteristics of simple resistor-only and inductor-only AC circuits. We will now investigate the effects of combining the two components together.

Passive circuits for power factor correction (PFC) are simple, reliable, robust, and they don't generate EMI [1-4]. Plus, they offer a low-cost alternative for complying with harmonic current limit ...

It’s a story we’ve told dozens of times already. The cost to manufacture a handful of circuit boards has fallen drastically over the last decade and a half, which has allowed some interesting ...
