Lamp dimmers and their circuits must be compact, energy efficient and able to operate reliably in confined spaces. Lamp brightness is varied by controlling the conduction time of each half-cycle of ...

This article brings control theory to life. Too often control theory is taught using block diagrams with no reference to real ...

Substituting a diode for a resistor in a circuit powered by an AC line is typically an easy recipe for disaster, but it’s the precise challenge faced by designers seeking to replace incandescent lamps ...
