Switching ac power on and off has been a challenge since Edison and others started switching power more than 125 years ago. Now, a solid-state relay (SSR) uses a patented zero-voltage crossing ...

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 ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...
