Drive circuits for Power MOSFETs and IGBTs
www.st.comdriven 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
Fundamentals of MOSFET and IGBT Gate Driver Circuits ...
www.ti.comThe bipolar and the MOSFET transistors exploit the same operating principle. Fundamentally, both type of transistors are charge controlled devices, which means that their output current is proportional to the charge established in the semiconductor by the control electrode. When these devices are used as
Insulated Gate Bipolar Transistor (IGBT) Basics
www.ixys.comThe Insulated Gate Bipolar Transistor (IGBT) is a minority-carrier device with high input impedance and large bipolar current-carrying capability. Many designers view IGBT as a device with MOS input characteristics and bipolar output characteristic that is a voltage-controlled bipolar device. To make use of the advantages of both Power
