500kW PSM短波发射机可编程控制功率模块的研制

Development of Programmable Power Module for 500kW PSM SWTransmitter

500kWPSM短波发射机可编程控制功率模块,是瑞士ThalesBroadcast&MultimediaAG公司TSW2500型500kWPSM短波发射机调制器的主要组成部分,每部发射机装有26块。此种机型在同类产品中有显著的先进性,成为我们对外广播的主力机型。可编程控制功率模块的研制,是为了解决该机型备件国产化而进行的研发项目之一。该项目于2001年底立项开始研制,2002年9月第一块样品上机试验,2003年完成小批量生产试用获得成功。现已通过标准计量产品鉴定,并获总局科技进步一等奖。

The numerous TSW2500 type PSM SW Transmitters introduced into the 襎ibet-Xinjiang Project?are far more sophisticated than other types and have become themain ones for overseas broadcasts. The Radio Bureau, SARFT, started to developthe domestic programmable power module since 2001, that has now passed theformal test and has won the SARFT 2003 first scientific and technological award.The characteristics, system composition and process of concrete implemetation ofthis developed module are introduced in more detail.
