Insulated Gate Bipolar Transistors

1998
In this chapter, the basic structure and operating characteristics of the IGBT are first described. The analysis of forward and reverse blocking capability is then performed followed by discussion of the on-state characteristics of IGBTs with various collector structures.

Recent advances in insulated gate bipolar transistor technology

IEEE Transactions on Industry Applications, 1990
Device design of the insulated gate bipolar transistor (IGBT) has been optimized to reduce the distributed transmission-line effect. In addition, cell geometry is chosen to yield high latchup current capability and low forward-voltage drop simultaneously. The vertical structure is optimized to enhance both the turn-off speed and the safe operating area

Latch-up prevention in insulated gate bipolar transistors

[1993] Proceedings of the 5th International Symposium on Power Semiconductor Devices and ICs, 2002
A technique for improving the latch-up capability of the LIGBT (lateral insulated-gate bipolar transistor) is proposed. A shallow trench at the cathode is used to reduce the p-base resistance and eliminate the p-well resistance, and consequently prevent the device from latching-up at low voltages.

Analysis of double trench insulated gate bipolar transistor

Solid-State Electronics, 1995
Abstract Numerical simulation is used to analyse a novel Double Trench Insulated Gate Bipolar Transistor (DT-IGBT) structure. It has been found that the DT-IGBT structure can be used to achieve a switching loss similar to that of the power MOSFET transistors.

A dynamic n-buffer insulated gate bipolar transistor

Solid-State Electronics, 2001
Abstract A novel dynamic n-buffer insulated gate bipolar transistor (DB-IGBT) with double gates is proposed and analysed in detail by using two-dimensional numerical simulations. It is found that the turn-off energy loss of this device is reduced and the short-circuit performance is improved significantly compared to the optimised conventional IGBT ...

Series Connection of Insulated Gate Bipolar Transistors (IGBTs)

IEEE Transactions on Power Electronics, 2012
High-voltage switches required in present power electronics applications are realized by connecting existing devices in series. Unequal sharing of voltage across series-connected devices can be minimized by using active gate control techniques, snubber circuits, and active clamping circuits.

Lateral Unidirectional Bipolar-Type Insulated-Gate Transistors

Japanese Journal of Applied Physics, 1983
A lateral unidirectional bipolar-type insulated-gate transistor (Lubistor) is proposed which has a lateral p +-n-n + (or n +-p-p +) diode structure on the top of the insulator and in which the insulated gate is aligned in the n (or p) region and the thickness of the n (or p ...

Performance Assessment of 4H-SiC Bipolar Junction Transistors and Insulated Gate Bipolar Transistors

Materials Science Forum, 2006
The performance prospects for 4H-SiC Bipolar Junction Transistors (BJTs) and Insulated Gate Bipolar Transistors (IGBTs) are theoretically evaluated. The total power dissipated (Ptotal) for both devices is calculated as a function of lifetime in the drift region and blocking voltage and used as a figure of merit to compare and contrast the effectiveness

A novel high performance insulated gate bipolar transistor

Solid-State Electronics, 2006
Abstract For the first time, a new concept of LDE-IGBT (local drift-region enhanced IGBT) is proposed and verified by two-dimensional (2D) device-circuit mixed simulations. The structure of the proposed device is almost identical to that of the conventional IGBT, except for an additional n + plugged region under the gate contact. The proposed device
