Providing modern electronic devices with a diet of healthy power is not straightforward. Small AC-connected equipment often uses a capacitor-input filter following a half- or full-wave rectifier.

A simple circuit monitors the elapsed time over which a line-connected ac load energizes (Figure 1). You can then access the elapsed-time count over a standard one-wire protocol. When you energize the ...

When selecting a power supply, one of the most important functional requirements of the product is its EMI performance. AC/DC power supplies are the interface between the end-product electronics and ...
