Title VDMOS speed control system based on the main circuit template of the design and development
Abstract
Power electronics technology is applied in the field of power electronics, the project known as the application of power electronics technology. It is using high-power electronic devices to control power to transform and to study the contents, is an electronic, control and power is closely related to the brink of disciplines. The power of modern electronic technology direction of development, from the low-frequency technology to deal with problems mainly of traditional power electronics, to the high-frequency technology to deal with problems mainly of modern power electronics direction of change.
VDMOS power field-effect transistor is abroad 1980s with the rapid development of a new power devices. A fast switching speed, high input impedance, thermal stability, and no secondary breakdown, and other advantages, can be used for AC / DC switching power supply, laser power, plasma power, radar power, uninterruptible power supply and motor speed, and other fields. In saving energy and military aspects of the national economy and have broad prospects and a good social and economic benefits. VDMOS the use of energy-saving devices, the provincial timber, reducing the size of the effect, particularly in the power electronics technology, make it possible for the power control system and transform circuit innovation, in the national economy and the military has a broad prospect and a good social Economic benefits.
