Explanation of how a diode divider can tame powerline noise on a zero-crossing detector's input circuit, improving ZCD sensitivity.
This design idea explains how a zero-crossing detector circuit can be used to control triacs.
There are two 600V-protected detection blocks: zero crossing and reservoir capacitor voltage. Zero-crossing Via separate diodes, the two zero-crossing detector pins connect direct to the live and ...
A while ago I needed a piece of test gear – an isolated way to transfer zero-crossing information from a variable ac power source: The exact zero crossing point is not important in this application, ...
