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 ...
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 ...
A snubber circuit limits voltage spikes in power converters. Snubbers are also used in the output of Class-D audio amplifiers for the same reasons (Fig. 1). When the transistor you use to switch the ...
