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 ...

AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC ...
