Brief Introduction of IGBT Technology
Working Principle of IGBT
IGBT (insulated gate bipolar transistor) is a kind of power electronic device, which combines the high input impedance of MOSFET (metal-oxide-semiconductor field effect transistor) with the high current endurance of bipolar transistor (BJT). Generally speaking, it allows large current to pass and switch quickly, making it especially popular in applications such as frequency conversion and motor drive.
- Switching: IGBT the switching speed of is relatively fast, especially at low voltage. This makes it perform well in high frequency applications.
- Conduction mode: When the IGBT is turned on, the voltage drops to a fixed value regardless of the current, which makes it keep low conduction loss under high current.
- Cut-off mode: In this mode, IGBT has almost no conduction current, thus realizing efficient current control.
Comparison of IGBT and Other Semiconductor Devices
- Compared with MOSFET IGBT has lower conduction loss in high voltage and high current applications, but the switching speed is slightly slower. Therefore, MOSFET may be more suitable for applications requiring fast switching.
- Comparison with BJT IGBT has higher input impedance and does not need continuous base drive. In high current applications, IGBT has lower conduction loss than BJT.
- Compared with SiC and GaN devices These are new semiconductor devices based on silicon carbon (SiC) and gallium nitride (GaN). They have advantages in high frequency and high temperature applications, but the cost is relatively high at present. IGBT still has advantages in medium and low frequency and high current applications.
