Use of IGBT in Hybrid Electric Vehicles and UPS

One of the rapidly growing and diversified industries is the automotive manufacturing, which is the largest with a broad extent in consumer preferences for model, easement and innovation. Everyone will profess that severe urban pollution is occurred by the gasoline powered vehicles when these consume dwindling fossil fuel resources. Expansion of electric and hybrid-electric vehicles is the most effective solution of this problem. We have to face serious technological challenges to achieve the worldwide goal to lessen the CO2 discharge and fuel consumption with pioneering endeavors in evolving electric vehicles (EVs) and hybrid electric vehicles(HEVs).

Motor drives based on IGBT (Insulated Gate Bipolar Transistor) have been used in all hybrid-electric and electric cars introduced into the market until now. IGBTs play the major role in new powertrain generations like EVs and HEVs to drive the electric motor or gather the energy. IGBTs are vulnerable to heating issues because they run at very high frequencies and under high power. Thermal characterization helps to optimize the IGBTs layout, structure and mounting to optimize its performance.

All hybrid-electric and electric cars that have been introduced into the market so far have relied up on 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. After all we can say, the availableness of IGBTs has been diametrical to the advancement of the hybrid vehicles and to the expansion of the charging substructure for the electric vehicles. Because of the unique characteristics, IGBTs will continue playing a very important part in the availability of cost deducting technology for the entire hybrid and electric vehicle business.

The manufacturers of Uninterruptible Power Supplies face enormous contest as the UPS market is immensely competitive. Endeavors to uplift the performance and dependability of UPS units are going on constantly. A UPS can survive in the market if the components used in it can keep pace.

Spontaneous control, outstanding switching features and excellent reliability make IGBTs the perfect option today for medium and high-power UPS. These modules greatly enhance UPS performance, specifically in terms of proficiency, acoustic noise, shaped and weight.

In high capacity UPS where the inverter functions between 2 and 4 kHz, the prime benefit of the IGBT is simplification of transistor control (better reliableness). IGBT is comparable to the bipolar transistors in terms of efficiency.

In medium capacity UPS, which are often seen in computer rooms, the acoustic noise criterion makes it essential to eliminate the 50 or 60 Hz transformer and to attach an inverter operating at a frequency of 16 kHz, thus making the IGBT completely inevitable both because of the lessening in number of elements needed to control it and because of the increase in weight and aggregate dimensions.

Exceptional switching speed, effortless control and overload resistance of the IGBT make it a component of noteworthy interest in modern times.
