Usage of IGBT in Electric and Hybrid Vehicles

The rapidly-growing and diversified automotive industry is the largest in the world because of an extensive range in customer preferences for comfort, design and technology. At present, for commuting, transportation of merchandise, recreation and shopping purposes, gasoline powered cars are still preferred in our society. But we all know it well that gasoline powered vehicles provoke acute environmental pollution during the time of consuming declining fossil fuel provision. Expansion of hybrid-electric and electric vehicles is a resolution to this problem. The worldwide goals to reduce fuel depletion & emissions, with pioneering attempts in developing electric vehicles (EVs) and hybrid electric vehicles (HEVs), bring significant technological challenges.

The IGBT (Insulated Gate Bipolar Transistor) has a vital influence on the transportation sector in all over the world. It allowed the introduction of dependable & cost effective electronic ignitions systems that have enhanced gasoline fuel efficacy by at least 10 percent. They have also been major elements in the improvement of mass transit systems and the deployment of electric and hybrid electric vehicles.

IGBT is playing the prime role in the new era of hybrid and electric vehicles. All hybrid-electric and electric cars that have been introduced into the market so far have relied upon IGBT-based motor drives. In new powertrain generations such as EVs and HEVs, IGBTs play the key role in order to drive the electric motor or store the energy. IGBTs run at very high frequencies and under high power which makes them vulnerable to thermal problems. Thermal characterization helps to optimize the IGBTs layout, structure and mounting to optimize its performance.

Mass transit systems within cities must depend on buses, trams, and underground trains. To lessen urban pollution, gasoline powered buses are being replaced with electric buses in many cities. All of these below requirements were met by using the IGBT-based motor drive in control system for the electric transit bus: (a) wide range of speed including high operating speed; (b) large startup torque for good acceleration; (c) high efficiency; and (d) regenerative braking to increase utilization of batteries. In Europe and Japan, electric tram transit systems have been modernized by using IGBT-based motor drives. According to AEG-Westinghouse Transport Systeme, Germany, the low floor concept is becoming a standard customer prerequisite. This has been enabled by today’s IGBT modules.

After all we can say, the availability of IGBTs has been diametrical to the advancement of the hybrid vehicles and to the expansion of the charging substructure for the electric vehicles. IGBTs will carry on playing a significant part in the availableness of expense reducing technology for the whole hybrid and electric vehicle business.
