Two new patented circuits control ac power to resistive and reactive loads with minimal EMI. They are applicable to single and multiple ac phases and varying ac frequencies. Switching ac power on and ...

A “constant-fraction discriminator” usually performs the time-tagging of impulsive events, which have a peaking time of the signal amplitude. The implementation of this technique requires a delay in ...

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 ...

This report describes circuits employing CAPZero that provide zero crossing/line frequency and AC Loss information whilst also providing the normal CAPZero X capacitor discharge function with no ...

For one-off projects or prototyping, it’s not too hard to find a wall wart or power supply to send a few joules of energy from the wall outlet to your circuit. Most of these power supplies use a ...
