IGBTs Are helping CNC Plasma Cutting Machines

CNC machines with IGBTs are fast.

The CNC plasma cutting machine is one such device that has made the complex welding process simple and efficient. They are computer numerically controlled machinery which has been of great use to the metal working industry since a long time. Metals are used in every field of our lives making plasma cutter necessary equipment in the metal industry. If you deal with steel or metal, great plasma cutters are definitely music to your ears. CNC plasma cutters with IGBT transistors are fast and can start cutting instantly. These cutters are multipurpose, susceptible of penetrating and complicated cutting. These are able to cut any metal up to 6″ thick precisely. IGBT based plasma cutters are better than MOSFET based cutters in many aspects. With paralleled MOSFETs, if one of the transistors activates prematurely it can lead to a cascading failure of one quarter of the inverter. A later invention, IGBTs, is not as subject to this failure mode. IGBTs can be generally found in high current machines where it is not possible to parallel sufficient MOSFET transistors. IGBT plasma cutters are more costly but if you give emphasis on the cutting speed and quality then it’s the ultimate choice for you.

No preheating is necessary, so the torch can start cutting instantly. With speeds up to 500IPM, it can rival laser cutters based on the type of part. These cutters are versatile, capable of piercing, complicated cutting and beveling in one process. These can successfully cut any electrically conductive metal up to 6″ thick. Precision cutting is one of the attributes of CNC plasma cutters. These machines are paired with state of the art software and high accuracy components; the want for expensive secondary operations is eliminated. The torch head is computer controlled, making clean, sharp cuts. Tight integration between the cutting torch and software results in high superiority manufacture, high cut quality, fewer dross and high superiority edges. An IGBT based CNC engine may seem complex, the CNC (computer numerically controlled) software takes most of the guess work out of cutting. With a state of the art package, even a first time worker is capable of creating wonderful outcome. The machines are safe too, most systems offer an exhaust or down draft system to draw smoke away from the operator.

IGBT based plasma cutters create a warmth affected region and harden the edges of the material being cut. Many plasma cutting parts contains some dross that wants to be cleaned from the part but this has been minimized with today’s plasma cutting systems with elevated performance. CNC plasma cutters can cost more, but faster cutting speed and higher cut quality permit for earlier making with less labor intensive secondary operations. The long term efficiency and accuracy are elements which figure into the overall price of a plasma cutter, not simply the price.

Space Elevator To Mars Using IGBT Application Technology

One day we may need a space elevator to visit Mars using the IGBT technology. People heading into space in the near future could be travelling by elevator rather than rocket if Obayashi Corporation has its way. The company announced two years ago that it has the capacity to build a space elevator — and have it up and running by the year 2050.

The company said that the elevator would reach 96,000km (59,652 miles) into space and use robotic cars powered by magnetic linear motors (maglev, as seen in high-speed rail lines around Asia and Europe) to ferry cargo and humans to a new space station.

Great switching speed is required for PWM VFD operation which can be achieved by using IGBT (insulated gate bipolar transistor). IGBTs are susceptible of switching on and off several thousand times a second. A VFD IGBT can turn on in less than 400 nanoseconds and off in approximately 500 nanoseconds. A VFD IGBT consists of a gate, collector and an emitter. When a positive voltage (typically +15 VDC) is applied to the gate the IGBT will turn on. This is similar to closing a switch. Current will flow between the collector and emitter. A VFD IGBT is turned off by removing the positive voltage from the gate. During the off state the IGBT gate voltage is normally held at a small negative voltage (-15 VDC) to prevent the device from turning on.

All recent VFDs use IGBTs as power devices. These devices make it feasible to reduce annoying audible noise by using switching frequencies beyond the audible range. Unfortunately, VFDs using IGBTs, present a high potential for generating RFI – Radio Frequency Interference. Fast switching in these devices generates sharp-edged waveforms with high frequency components that generate more RFI. The most likely complaint is interference with AM band radios 500-1600 Khz. Nonetheless, sensitive computers, medical equipment and other noise-sensitive devices sharing the same power buss could experience serious interference.

In ultimate cases, the VFD itself can experience electrical noise interference. If elevator machine room equipment is not correctly laid out and properly wired, the electrical noise preached by the elevator VFD system can interfere with the elevator controller.

History of IGBT and it’s Impact in Our Life

http://www.uscomponent.com/history-igbt-impact-life/

The full form of IGBT is Insulated gate Bipolar Transistor. It is a three terminal power semiconductor device basically used as an electronic switch which can maintain high efficiency during fast switching. It has been utilized in many recent appliances: Electric cars, trains, variable-frequency drives (VFDs), variable speed refrigerators, air-conditioners, stereo systems with switching amplifiers and even lamp ballasts and vacuum cleaners.

The IGBT is a hybrid device obtained by the integration of a BJT and a MOSFET in a

Darlington configuration. The IGBT allows a great reduction of conduction losses even for high voltage rating (low on-state resistance), low power gate drive losses (insulated grid) and it can switch today in of less than 100 ns, whereas only 3 μs about 20 years ago. In addition, the current density of IGBT is 20 times larger as compared to MOSFET and 5 times as compared to BJT. The IGBT is, basically, a horizontal channel and vertical current MOSFET cell (VDMOS), except for the N+ Drain layer, which is substituted by a P+

layer at the collector.

The IGBT is a semiconductor device with four variable tiers (P-N-P-N) that are handled by a metal-oxide-semiconductor (MOS) gate structure without resurgent operation. This way of action was first introduced by Yamagami in his Japanese patent S47-21739, which was filed in 1968. This method of action was initially reported as an experiment in the lateral four layer device (SCR) by B.W. Scharf and J.D. Plummer in 1978. This method of operation was also experimentally revealed in vertical device in 1979 by B. J. Baliga. Plummer filed a patent application for IGBT mode of operation in the four layer device (SCR) in 1978. USP No.4199774 was issued in 1980 and B1 Re33209 was reissued in 1995 for the IGBT mode operation in the four layer device (SCR).

An identical device was invented by Hans W. Becke and Carl F. Wheatley for which they filed a patent application in 1980, and which they referred to as "power MOSFET with an anode region". This patent has been called "the seminal patent of the insulated gate bipolar transistor."

Hands-on devices susceptible of operating over an extended current extent were first reported by Baliga et al. in 1982. An alike paper was also presented by J.P. Russel et al. to IEEE Electron Device Letter in 1982. The applications for the device were initially regarded by the power electronics community to be severely restricted by its slow switching speed and latch-up of the parasitic thyristor structure inherent within the device. However, it was demonstrated by Baliga and also by A.M. Goodman et al. in 1983 that the switching speed could be adjusted over a broad range by using electron irradiation. This was followed by demonstration of operation of the device at elevated temperatures by Baliga in 1985.

Complete suppression of the parasitic thyristor action and the resultant non-latch-up IGBT operation for the entire device operation range was achieved by A. Nakagawa et al. in 1984. Today, IGBT modules are available with the capability of handling over 1000-amperes and sustaining more than 5000-volts.

The performance of IGBT advances gradually with the development of technology as it is a fairly modern invention. In power applications, bipolar transistor has already been replaced completely by IGBT; a power module is within reach in which several IGBT devices are attached in parallel, making it compatible for power levels up to few megawatts, which thrusts farther the limit at which thyristors and GTOs turn out to be the only option. According to its working principle, an IGBT is a bipolar transistor primarily, guided by a power MOSFET; it has the benefits of being a minority carrier device (satisfactory performance in the on-condition, even for high voltage apparatuses), with the high input impedance of a MOSFET (a very small volume of power can operate it on or off).

Nowadays, IGBTs are extensively used in industrial, medical, consumer, transportation, financial, aircraft and renewable power generation sectors of the economy.  This lead to increased ease, favor and standard of life for billions of people all over the world. Over the last 20 years, the growing influence of the advanced efficiency of IGBT-powered applications have been a total worth saving of $ 2.7 Trillion for U.S. customers and $ 15.8 Trillion for global customers. Besides this, the promoted effectiveness generated by IGBT-powered applications has produced an aggregate diminution in carbon dioxide emissions by 35 Trillion pounds in the United States and 78 Trillion pounds globally by the last 20 years. We can’t deny the role of IGBT to make a viable worldwide society with uplifted living norms along with alleviating the environmental influence.

At this moment, few manufacturers are the major product providers for the global market of IGBT. Infineon (Formerly Eupec), Fuji Electric, Mitsubishi, Powerex, Semikron, Toshiba etc companies are leading the IGBT world now.
