Integrated Gate Bipolar Transistors (IGBT) Performance Reaches New Levels

IGBTs (Integrated Gate Bipolar Transistors) have now been around for 30 years or so and have played a very useful role in their capacity as a key component in power switches, particularly at high voltages. However, the use of IGBTs has been eclipsed somewhat by power MOSFETs for applications where the switching frequency is at the high end of the power spectrum – greater than 100 kHz. However, that has now changed. IGBT research and development has come up with improvements in IGBT design which mean that these components are now able to handle the frequency range and temperatures which are being demanded by more and more applications.

The new IGBT design is an extremely thin IGBT, fabricated on a wafer structure, which is reported to have a blocking voltage of 650 volts. It is designed for DC to DC conversions of up to 200 kHz. These ultra rapid operating IGBTs are now more than a match for their competitors in the high end semiconductor market.

The superiority of SJ MOSFETS challenged by new version IGBTs

Up to the recent development phase of these ultra thin wafer IGBTs, superjunction (SJ) MOSFETS have been the semiconductor of choice for those applications requiring tolerance to both high temperature and high switching frequency. SJ MOSFETS have actually had a better performance record for these sorts of applications than conventional power MOSFETS as well as IGBTs which have lagged behind in performance. The new IGBT design is touted as matching the performance level of SJ MOSFETS in terms of switching capacity but the main advantage is that the manufacturing process is simpler, making these components much more competitively priced compared to their competitors. Another comparison between the new IGBTs and SJ MOSFETS gives the IGBTs a clear lead in terms of their Tjmax, which is 175oC, compared to that of the SJ MOSFETS at 150oC.

IGBT structure improvements

The key improvement of these IGBTs is their fabrication process. They are fabricated on an extremely thin wafer of around 70μm using a punch through structure. This design permits the components to incorporate a collector which is only lightly doped. This means that they have less stored charge and consequently much improved switching performance – as has already been mentioned. They are rated up to 200 kHz, which is a doubling of the performance of their predecessors.

One of the inherent problems inherent in older style IGBTs was the fact that electron irradiation or metal doping was used to enhance switching speed. The design has the in-built problem that as the operating temperature increases, the current tends to leak. This limitation has meant that IGBT have had a limited usage role when the Tjmax has been above anything like 150oC. The improvements in design have meant that temperatures up to 175oC and beyond are now tolerated.

At this temperature the leakage of current is very much reduced compared to older style GBT designs. The new style IGBTs have a noticeably higher cell density which has a knock on effect on various other component properties. The lower voltage drop also accompanies a smaller gate capacitance. This combination means that the minimal internal gate resistance still means that the components are capable of the reported doubling of switching speed.

Characteristics of Integrated Gate Bipolar Transistor (IGBT)

IGBTs or integrated gate bipolar transistors to give them their full name are semiconductor components with highly specific uses. They are similar in a way to power transistors but have significant differences in the way they are controlled. Power transistors are controlled by the amount of current flowing across their base in contrast to IGBTs which are controlled by the voltage applied to their gate. The characteristics of the IGBT make them more of a combination of a power transistor and a MOSFET (metal-oxide semiconductor field effect transistor).

The IGBT is most commonly used in applications where high frequency power switching is needed. One of the reasons why the IGBT works well for this purpose is that only a tiny amount of current is needed applied to its gate. The current is only very small because of high impedance at the control gate. IGNTs are not only able to be switched much more rapidly than other types of semiconductor but they also have other desirable characteristics, especially the fact that they can be used at high voltages.

High power, high frequency devices work by turning the current on and off rapidly with the help of a switching device. Apart from IGBTs, other switching components include MOSFETS and bipolar transistors. An oscillating device is used to control the IGBT or other type of switch.

One common application of IGBTs is in a high voltage electric motor. The voltage used by the motor is converted from DC to AC with the IGBT controlling the frequency at which the AC is provided. There are three different types of motors which may have IGBTs incorporated into their control device. These are,

A three phase induction type motor

A three phase brushless motor with sinusoidal BEMF

A three phase brushless motor with trapezoidal BEMF

The motor drive may be either of a sinewave or squarewave type. Sinewaves are preferred where RF interference might be a nuisance, although squarewave drives are actually the more efficient of the two. Of the three motor types, the first one, the induction motor tends to have a sinewave type drive, although there are high and low pulses in any wave phase noticeable.

The other two types of motor use magnets instead of rotors that are found in induction motors. These motor types are somewhat more expensive than induction motors, but more efficient. The main difference between the two types of brushless motor is the type of wave produced by their drives: some are trapezoidal, others are sinewave. In all these motors, there are three phases involved and six transistors. MOSFETs tend to be the preferred choice at lower voltages, say 200 volts or less, but for higher voltages, the IGBTs are preferred. IGBTs can handle voltages of up to 1200 volts.

IGBT and its Usage in Motor Control

http://www.USComponent.com/igbt-usage-motor-control/


The IGBT, Insulated Gate Bipolar Transistor, is a switching transistor that is driven by voltage applied to the gate terminal. Device structure and operation are identical to those of an Insulated Gate Field Effect Transistor, generally known as a MOSFET. The primary dissimilarity between the two device types is that the IGBT uses conductivity modulation to reduce on-state conduction losses which MOSFET does not do.

IGBT is a device that integrates the voltage feature of a bipolar transistor (collector – emitter) and the drive feature of a MOSFET. The key reason behind the flourishing popularity of IGBT is its superiority at high speed switching applications. This device is well-known for integrating high efficiency and fast switching. It is mainly used as an electronic switch in many modern appliances: variable-frequency drives (VFDs), electric cars, trains, variable speed refrigerators, air-conditioners and even stereo systems with switching amplifiers. Today we will discuss about usage of IGBT in motor control.

Advancements of highly capable motor drives are very essential for industrial applications. Satisfactory dynamic speed command tracking and load regulating response are two must needs, for a high performance motor drive system. DC motors excel in terms of speed control for acceleration and deceleration. The power supply of a DC motor joins right away to the field of the motor which approves for accurate voltage control, and is required for pace and torque control applications. Because of their simpleness, ease of application, dependability and auspicious cost, DC drives have long been a mainstay of industrial applications. Because of low horsepower ratings, DC drives are usually less costly in comparison with AC drive systems. DC motors are being used as adjustable speed machines traditionally and an extensive extent of options has developed for this intention.

To obtain sufficient levels of power handling capability, especially in motor control applications those demand multiple drive elements, power integrated circuits have been developed using hybrid constructions of the distinct transistors. Hybrid techniques have been necessary and useful due to the power handling limitations of monolithic power integrated circuit technology. Power integrated circuit design has often been limited by the absence of power packages that provide the low thermal impedance and high performance switching necessary for reliable operation. The switching elements of these modules, which may be Insulated Gate Bipolar Transistors (IGBTs) or various forms of thyristors, “chop” low-frequency (e.g., 60 Hz or dc) voltages /currents at the input / output port into high-frequency square wave pulses of variable width (20 to 200 ms).

The silicon GTO was the only available power semiconductor switching device until the 1990s. It had power conducting ability compatible for motor control applications. The ratings of IGBTs had adequately developed in the 1990s. It overcame one Megawatt which allowed entrance of the IGBT into the traction market. The availableness of the IGBT made allowance for notable advancements in the motor drive technology due to exclusion of snubber circuits and an raise in the operating frequency of the inverter circuit employed to transfer power to the motors.

The insulated-gate bipolar transistor (IGBT) is a functional integration of Power MOSFET and BJT devices in monolithic form. It combines the best attributes of both to achieve optimal device characteristics. The IGBT is a three-terminal power semiconductor device primarily used as an electronic switch that can essentially combine high efficiency with fast switching much like the MOSFET.

History of IGBT

First-Generation of IGBTs was on 1980s to early 1990s were prone to failure through such modes as

-latch-up (in which the device will not turn off as long as current is flowing)

-and secondary breakdown (in which a localized hotspot in the device goes into thermal runaway and burns the device out at high currents).

Second-generation devices were ameliorated, and the current third-generation ones are even more refined, with speed rivaling MOSFETs, and excellent ruggedness and tolerance of overloads.

Comparison with MOSFET

An IGBT features a significantly lower forward voltage drop compared to a conventional MOSFET in higher blocking voltage rated devices.

IGBTs are favored by high voltage, high current and low switching frequencies while MOSFETs are better for handling low voltage, low current and high switching frequencies

The IGBT is a semiconductor device with four alternating layers (P-N-P-N) that are controlled by a metal-oxide-semiconductor (MOS) gate structure without regenerative action. The additional P-N junction blocks reverse current flow. This means that unlike a MOSFET, IGBTs cannot conduct in the reverse direction. In bridge circuits, where reverse current flow is needed, an additional diode is placed in parallel with the IGBT to conduct current in the opposite direction. The penalty isn't overly severe because at higher voltages, where IGBT usage dominates, discrete diodes are of significantly higher performance than the body diode of a MOSFET.
