IGBT is the core of electric vehicle control system which determines the energy efficiency of the vehicle.The main international manufacturers are "Siemens, infineon, mitsubishi, Toshiba" these big old factories.Among them, "high-voltage and high-power IGBT" is the core of the electric vehicle power system. Currently, there are only two domestic enterprises that can mass produce high-voltage and high-power IGBT chips and apply them to vehicle production.1. BYD (new energy vehicle), 2.CRRC(High Speed Rail).
IGBT (insulated gate bipolar transistor) is a kind of compound full control voltage drive type power semiconductor devices, as the world recognized the power electronics, typical products of the third technological revolution with high frequency, high voltage, high current, excellent properties, such as easy to switch is the industry known as "CPU" power converter device.As a fusion of many high-tech in one master, IGBT has large-scale application in electric vehicles, industrial frequency conversion control, locomotive traction, consumer electronics and other fields, but the IGBT market has been monopolized by foreign companies in China, especially the core technology of IGBT chip design and manufacturing.
Because the IGBT has high voltage high frequency, such as performance, but there is a spare parts NTC thermistor chipmeasuring temperature, Exsense company NTC thermistor chip with high precision and reliable.It is very suitable for this type of power semiconductor IGBT to measure temperature, different size different parameters can be directly customized according to customer requirements.
