driven switches, because their insulated gate behaves like a capacitor. Conversely, switches such as triacs, thyristors and bipolar transistors are “current” controlled, in the same way as a PN diode. 2.2 Driving a gate As shown in figure 2, driving a gate consists of applying different voltages: 15V to turn on the device
