摘　　要：改进了调压控制系统以实现工频倍加型电子加速器的高压稳定调节。该系统采用伺服电机驱动柱式调压器进行调压,可编程控制器作为逻辑控制单元,工控机实现人机交互,采用闭环和开环方式实现高压调节控制。实验证明,该控制系统的响应速度、稳定度及调压精度较传统调压系统均有较大改进,能满足性能要求更高的电子加速器的控制要求。Voltage stability and precision are key specifications of an electron beam irradiator. A voltage control system was developed for smooth high voltage regulating on a power frequency electron accelerator. Pillar variac driven by servo motor was used as the regulating device, with a programmable logic controller as the control unit. An industrial PC was employed to realize human-machine interaction. Open-loop and closed-loop modes were employed to regulate the high voltage. Experimental results show that the speed, stability and precision for high voltage regulating were improved greatly, hence a much better performance of the electron accelerator.
