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

High-wattage resistors often are used as test loads for power transformers. Resistors don’t introduce phase shifts, and it’s easy to check that a transformer’s voltage regulation remains within spec ...

Although variable DC power supplies might appear to be relatively simple devices common to every engineer’s benchtop, they are actually sophisticated instruments. They must reliably deliver voltage ...
