| 摘 要： | X射线高压发生器控制电路采用电压和电流两路负反馈回路对高压发生器进行控制,同时通过两个可调电阻实现精确微调。在X射线高压发生器控制电路内部,采用ADUC842单片机对X射线高压电源智能控制系统运行状态进行实时监控,同时通过对反馈值直接系数校准的方式,忽略内部元件的偏差,实现精确设置。内部采用的ADUC842为用户提供一个便捷的软件接口,方便用户二次开发。

| Abstract: | Voltage and circuit negative feedback is used to control the high-voltage generator in an X-ray high-voltage generator control circuit, re-alizes accurate fine tuning by using two adjustable resistances at the same time. In the inner part of the control circuit, uses an ADUC842 microchip to monitor the running states of the X-ray high-voltage power supply intelligent control system, and with direct coefficient tun-ing of the feedback value, the inner component deviation can be overlooked, so that realizes accurate setting. The utilization of ADUC842 provides the user a convenient software interface, makes it easy for secondary development. |
