applying different voltages: 15V to turn on the device through S1, and 0V to turn off the device through the gate through diode D1 is sufficient to charge the input capacitance C in and turn on the off the switch, a pulse is applied to the diode D2 which turns on T2, which in turn discharges the the pulse duration times required to turn the devices on and off are very small, this principle dimming circuits are controlled by TRIACs.
