现代电力电子学技术的迅速发展和大功率开关器件的出现使开关稳压电源在中功率雷达发射机中得到了广泛应用。目前，由于ＩＧＢＴ模块的推广应用和新的拓看望 技术的不断涌现，高压大功率开关稳压电源已开妈在现代雷达发射机中使用。本文简单介绍了１４０ＫＷ大在电源在某空间目标测量雷达发射机中的应用和其工程设计考虑。

With the speedy development of modern electric power and electronics technology, there appeared high power switching devices. In consquence, switching regulated power supplys are used extensively in middle power radar transmitters,. Presently, with the application of IGBT modules, new topology comes out continually, high voltage and high power switching regulated power supplys have been used in modern radar transmitters. In this paper, briefly introduces a 140kW high power switching power supply which has been applied in a space target measure radar transmitter as well as its engineering design considerations.
