What consumes more than half of the world's electricity and supports nearly every facet of industrial production? The answer is the AC induction motor. Although these motors typically tolerate ...

For as versatile and inexpensive as switch-mode power supplies are at all kinds of different tasks, they’re not always the ideal choice for every DC-DC circuit. Although they can do almost any job in ...

Using a “trick,” a switching or linear regulator can generate lower voltages than the feedback voltage. It requires another positive supply voltage connected to the resistive divider to adjust the ...

Editor's Note: Here's another take on the transformerless AC line power supply, which finds use in some well-insulated, low-power devices. Our technical reviewer pointed out that C ac should be an ...

Semiconductor memory, card readers, microprocessors, disk drives, piezoelectric devices, and digital systems create transient loads that voltage regulators must service. Ideally, regulator output ...
