Power MOSFETs enable current to flow exponentially in proportion to the controlling voltage and have revolutionized the switching of power electronics. Since they are available in low cost, have virtually no OFF-state losses and have wider bandwidths, these can be used in many switching applications. In terms of power converters, this technology has enabled us to build improved designs with higher efficiency, faster response and better regulation. This has also helped to achieve higher power supplies and better dynamic performance. A great example is TA-AU application field. TA-AU is an abbreviation for trench-assisted access uV MOSFETs (mosfet power)) technology. It is based on the technology developed by Toshiba Co., Ltd. Japan.

The basic principle behind TA-AU is the utilization of a very thin silicon layer deposited over trenches in the device structure. This layer forms the drain access region of the device. The use of the trench structure helps to minimize the drain charge generation and the resistance coefficient associated with it. This in turn helps to obtain improved efficiency, particularly when the device operates in the saturation region. The result of this approach is that power losses can be reduced considerably. Furthermore, the trench structure also simplifies the power flow in the transistor and the switching frequency can be increased.

The main advantage of TA-AU is that it eliminates the need of a conventional output diode. In addition, the high voltage ratings achievable are excellent. This type of device can be used for high voltage applications such as motor control and automotive applications. TA-AU technology is also extremely useful in applications such as phase control, bridge rectification, motor control, voltage boosting, etc. In applications such as these, TA-AU provides increased efficiency, higher reliability and better current handling capability than BJT technology.

Although any specific application can benefit from TA-AU technology, it is most suited for the design of high current, high voltage MOSFETs. The key advantage of this technology is its ability to reduce the ON-state resistance and power losses. This allows the designers to build better and more efficient circuits. Also, the higher ratings achieved are very advantageous in applications where current limitations need to be avoided. Furthermore, it enables the designers to make use of the best device topologies available.

In conclusion, TA-AU technology has revolutionized the world of power electronics. It has enabled us to build more efficient and reliable power converters and also to optimize the design of high power MOSFETs. The gadgets powered by this technology benefit from improved accuracy and efficiency. Also, this technology has helped to significantly reduce the amount of losses associated with the switching operations of power electronics. Therefore, it can be safely said that TA-AU technology is the cornerstone of modern switching electronics.
