Insulated Gate Bipolar Transistor (IGBT) is a relatively new device which is noted for its high efficiency and fast switching, making it ideal for applications where saving energy and protecting the environment are important factors. Consequently, IGBTs are found in hybrid vehicles and electric vehicles, in wind turbines and solar installations, as well as in smart grids and modern household appliances, such as refrigerators and air-conditioning systems. Although the automotive market is relatively small, the number of electronic components in automobiles is steadily rising. Hybrid and electric vehicles have the highest share of electronic devices. They need IGBTs for power control. The power control unit (PCU) in these cars regulates the transfer of energy between the battery and electric motor. Such PCUs can contain up to 20 IGBTs. IGBT usage in the car industry is expected to grow around 70 percent in 2015. When a hybrid-electric car is operated on highways, it operates with power delivered from both the gasoline-powered Internal Combustion Engine (ICE) and the battery-powered electric motor. In this case, IGBTs are needed to operate the ignition system of the ICE and to drive the motor. The battery in the hybrid-electric car must be recharged to renew the stored energy. This is also performed using IGBT-based circuitry in the power electronics module. In conclusion, the availability of IGBTs has been crucial to the success the hybrid electric car and to the deployment of the charging infrastructure for the plug-in electric vehicles. The IGBT will continue to play an important role in the availability of cost effective technology for the entire electric vehicle industry.

Numerical control (NC) is the mechanization of machine tools that are functioned by accurately programmed commands encoded on a storage mean, as against to run manually via hand wheels or levers, or mechanically automated via cams alone. Most NCs today are computer numerical control (CNC), in which computers play an integral part of the control. Fuji Electric delivers high-performance power semiconductors for energy, automotive, information technology, and industrial applications. IGBTs (Insulated Gate Bipolar Transistor) made my Fuji is used widely in CNC plasma cutters and welding machines. Plasma cutting involves cutting a material using a plasma torch. It is commonly used to cut steel and other metals, but can be used on a variety of materials. In this process, gas (such as compressed air) is blown at high speed out of a nozzle; at the same time an electrical arc is formed through that gas from the nozzle to the surface being cut, turning some of that gas to plasma. The plasma is enough heated to melt the material being cut and moves pretty fast to blow molten metal away from the cut. Arc and tube welding machines are mostly used in industrial setting for building and repair of the infrastructure. Welding power supplies are required to create an electric arc between an electrode and the base material to melt the metals at the welding point. The arc can be created by either DC or AC current with consumable or non-consumable electrodes. The welding region is sometimes protected by some type of inert or semi-inert gas. Arc welding is popular due to low capital and running costs. For arc welding, the voltage is directly related to the length of the arc, and the current is related to the amount of heat input with typical currents of 50 to 500 amps depending on the size of weld. For arc welding with low voltages and large currents, a soft switching PWM DC-DC power converter with Fuji IGBT switches in the primary side of a high frequency transformer is considered to be the most suitable topology for the welding power supply110, 111. Power losses in the Fuji IGBTs are reduced by using soft switching resulting in a volume reduction of 59% and weight reduction of 47% compared with the hard-switching approach. Dynamic welding performance is improved due to operation at 40-kHz when compared with 13-kHz with hard-switching. We have been selling IGBT power transistor modules since 2001.
