摘　　要：采用逆变电源和开关电源技术,设计了连续可调直流高压稳压电源和灯丝电流稳流电源,在此基础上,应用单片计算机,实现了X射线源的数字控制和监视,实验结果表明系统功能完善,技术指标达到了安检设备专用X射线源的要求。An X-ray generator works on high-voltage and low-voltage power supplies. In this paper, a continual adjustable DC high voltage power supply and filament current source were design based on switching power-supply technology and resonant inverter technology. Microcontroller was employed for the realization of the digital control scheme. Test results show that the X-ray source satisfies the requirements of security inspection equipment.
