Testing products designed to operate from ac power is not as simple as one might think. Consider a factory with the straight-forward need to manufacture and test the heating element for a toaster.

Overview: Voltage fluctuations are a common problem in many homes. Sudden spikes and drops can damage compressors, reduce ...

Many of today's applications require precision sampling analog-to-digital converters with resolutions of 12 bits or more, since the high resolution lets users make accurate system measurements. But ...

Solid-state ac supplies replace motor-generator and tap-changing transformers to offer the same tests at the push of a button • Solid-state ac-power sources combine the variable-frequency and ...

Designers have long used the gyrator circuit to create a virtual inductor employing readily available capacitors. The circuit can achieve high inductance values with relatively low capacitance values, ...

When you’re testing or debugging some mains-powered gear, plugging it directly into the outlet can often be an exciting proposition. If such excitement is not really your thing, you can opt for an ...

This three-part series describes how to properly test a DC/DC power supply, and ensure that it works reliably over various operating conditions. This series is intended to provide the designer with a ...
