Circuit description

Standard TRIACs have turn-off problems with inductive loads. Therefore, a high power alternistor is used here, also named as:

  • Snubberless triac
  • Three-quadrant triac
  • High commutation triac

The RC snubber network R14 and C4 protects the circuit from voltage transient spikes. The FTDI connector J2 is for re-programming. The ISP connector J9 is for burning the Arduino bootloader.
