摘　　要：介绍了一种设计X射线测厚用高压电源的新方法,将Buck电路引入高压电源用于前级直流电压调压,应用开关电源和移相全桥逆变技术,并且该系统以TMS320F2812为控制核心,使系统工作稳定。后级高压侧采用相控谐振和正负双向倍压整流电路,能大大减小纹波系数。该设计可实现稳定输出80 kV电压的高压电源。实验结果证明,该电源能够稳定工作,其性能满足设计要求。A new method to design high voltage power supply for the X-ray thickness measurement is described.The Buck circuit is introduced for pre-high-voltage DC power supply voltage regulator, and switching power supply technology and phase-shifted full-bridge inverter technology are used,TMS320F2812 is made as the control core of the system,to make the system more stable.The post-high-voltage side uses the phased resonance and positive and negative bipolar doubler rectifier circuit, can greatly reduce the ripple factor.This design of the high voltage power supply can allow for stable output voltage of 80 kV.The experimental results show that the power supply can work stably, theperformance can meet the design requirements.
