Several different technologies and designs are available among solid-state switches today. The major families are the standard Triacs (triode for alternating current), the snubberless Triacs, and the ...
Back to analog, let us start some Schmitt trigger experiments with jellybean bipolar junction transistors… This post explores the classic emitter-coupled Schmitt Trigger circuit. A Schmitt trigger is ...
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 ...
