AC Control¶

1. TRIACs: Low cost, high current handling capability.
2. Traditional relay: moving parts, relatively low cost, very high current
3. Solid State Relay: Higher cost, no moving parts. Advantage over TRIACs is that SSR can interrupt current at any point in the AC waveform. TRIACs only cut off current at the zero-crossing point.
