Development trend of power electronic devices in automobiles

Release date:2017-11-09 11:34 source: Views:

[Inner Mongolia Erdos Electronics Co. Ltd. the main SMD power inductors, plastic wire wound chip inductors, solid organic resistors etc.] with electronic, automotive intelligent degree more and more high, the sensors, MCU, ECU, IGBT, and BMS chip needs more and more. Undoubtedly, in these chips, the power electronic device is accounted for the absolute big head, then the future of power electronics devices in the car will show what kind of development trend?

"I think there will be four major trends, that is, high reliability, high integration, high power and productivity." Liu Wenxin, deputy senior manager of Technology Department of Toshiba Electronics (China) Co., ltd..

Infineon new energy automotive electric power application engineer He Yaohua recognized Liu Wenxin's judgment, but he also highlighted the following points.

First, special automotive grade power electronic devices will appear in the future. He explained that, although the automobile electronic components certification of the car factory is the default access conditions, through the certification of automotive grade products have a higher reliability and performance, but for general power electronic devices in industrial application design, development demand has not complied with the new energy vehicles change rapidly, has gone through the initial design "will use" stage, fine design has become a trend and necessity.

Two is platform design. Typical automotive electronic system development takes 2 to 3 years, if the subsequent update needs, push back to start the development, need to consume a lot of development costs and time. If power electronic devices can be implemented on platforms, the development cost and cycle can be significantly reduced.

Three is the intelligent and functional safety design. Power electronics is traditionally a passive actuator that receives instructions and moves. He Yaohua believes that the future trend is not only receive instructions simple, there are some judgment and protection functions, such as "to increase the current and temperature sensor inside the IGBT, when the system fails, can do preliminary judgment, to reduce vehicle output torque and speed, rather than directly off. In the battery voltage is high, reduce the power device switching speed, protection switch circuit safety, when the battery voltage is normal, do the most efficient switching action." Intelligent power devices allow electronic control systems to achieve higher security levels.
