高压直流电源与灯丝加热电源是影响X射线球管射线剂量、成像质量等因素的两个至关重要部分。基于Saber软件的仿真,设计制作了一台适应多种X射线球管供电的电源系统。系统输入电压为32 V,其中高压直流电源结合高频技术,采用负高压输出,具有放射小、不易击穿、易于X球管散热等优点,能够有效延长X射线球管的工作寿命。整个系统采用STM32作为控制,实现对高压直流源电压、管电流、高压工作脉宽的控制。最后将高压直流电源、灯丝加热电源与X射线球管整机安装在装有高压油的密封盒中。实验测试表明,该电源系统安全、稳定、高效率,达到了设计要求。

HVDCPS (High-Voltage DC Power Supply) and FHPS (Filament Heating Power Supply) are the most important parts influencing theperformance of X-ray tube, including the dosage of X-ray and imaging quality. This paper is based on the simulation of the Saber simulation software, a power supply system is designed and made and it can be adapted to various power supplies of X-ray tubes. The input voltage of the system is 32V, with high-frequency technology, using the negative high voltage output, having the advantages of small radiation, not easy to brea...
