I - CONVENTIONAL SOLUTION For many years the triac has been used to switch load on the AC mains and thanks to the low cost of microcontrollers ( m C the output port of the microcontroller and the triac as shown in the figure 1. Because of the low sensivity of the triac in the 4th quadrant this type of drive is often unpractical, and is replaced by the microcontroller, the triac had to be very sensitive and consequently was not able to withstand for example the
