From time to time I get requests to make some high power switching, so I decided to design a digital dimmer module that could handle a lot of different situations. The original requirements laid down ...

This design idea explains how a zero-crossing detector circuit can be used to control triacs. Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that ...

Rohm recently introduced a low-power 600V-tolerant zero-crossing detection chip, intended to cut energy wastage in home appliances by reducing sense current through the high voltage monitoring ...

Explanation of how a diode divider can tame powerline noise on a zero-crossing detector's input circuit, improving ZCD sensitivity. To properly control ac sources using solid-state devices, you need a ...

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 ...

We compared 2 bat detecting systems that use condenser microphones, 1 that performed computer analysis (Anabat6) of the output of a zero-crossing period meter (Anabat system) and the other that ...
