ctor parameters and gate drive details. Much of the performance of an individual IGBT in a specific application is determined by the mounting, printed wiring board, and surrounding component parameters, such as for inductors and transformers. To optimize a design, those components and the specific gate drive waveforms for the gates must be t
When an IGBT is installed and voltage is applied between the collector and emitter while the gate emitter connection is open as shown in Fig. 3-1, depending on changes in the electric potential of the collector, the current (i) will flow, causing the gate’s voltage to rise turning the IGBT on.
The most basic function of an IGBT is the fastest possible switching of electric currents, thus achieving the lowest possible switching losses. As the name “Insulated Gate Bipolar Transistor” reveals, an IGBT is a bipolar transistor with an isolated gate structure; the gate itself is basically a MOSFET.
