Design of the linear gradient of DC high voltage power supply based on X-ray machine

摘要

The emergence of technology which contains variable energy data acquisition and intelligent imaging has greatly accelerated the development of image acquisition based on X-ray. Although the emergence of this kind of intelligent technology improves the efficiency of working, the most are accomplished based on the software, and high voltage power supply itself is lack of controlling for the process of high pressure gradient, so that it can't focus on the process of data collection well. Demand on above, we put forward design of the linear gradient of dc high voltage power supply based on X-ray machine, the system of high voltage sccurce starts from hardware and software and solves the previous problem very well at the same time. The high-voltage source uses technology of PID control (Proportional-Integral-Differential Controller), it has the function of the automatic linear gradient of and the slope of process of high pressure gradient is adjustable, and it can get the feedback all the time, the precision and ripple of output are maintained within 0.1%. The development based on the function have been put forward and is in the research, its actual value is relatively significant.
