| Abstract: |
| 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. |
