Fig 1. This zero-crossing detector circuit generates the control pulses needed to turn on triacs that require negative pulses for switching. Fig 2. Designers can use ...

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 ...

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 ...
