Igbt minority carrier device
WebSimilar to other minority carrier devices there is a compromise between the on-state losses and faster switching speeds. The four-layer NPNP structure of the IGBT has a parasitic thyristor. Turn-on of this thyristor is undesirable, as it will lead to the loss of control by the gate. Ideally, once minority carriers are WebMultiple layers of P and N substrate give IGBT high conductivity, does not have body drain diode : Control : Voltage driven majority carrier devices, produces an electric field : Current controlled minority carrier devices, produces magnetic field : Uses : Can be used in digital and analog drives, both are used in off-the-shelf and custom servo ...
