摘要
介绍了一种应用DSP控制实现行波管高压电源的设计。通过应用TMS320F2812实现移相软开关技术和功率因素校正(PFC)技术,降低了电源的开关损耗和整体尺寸。分析了控制原理,并且说明了基于DSP的移相控制方法。
A design method to realize the high voltage power supply applied to the travelling wave tube (TWT) based on DSP( Digital Signal Processor) control is introduced. By applying phase -shifted full- bridge and soft switch technology and PFC (Power Factor Correction) technology, the switch loss and the whole size of the power supply are reduced. The control theory and phase - shifted control method are also analysed.
