摘　　要：设计了一个基于实验物理及工业控制系统(EPICS)实时测控的伺服电源控制器,并将其插入现有脉冲电源测试。该电源控制器采用死区时间调制(DTM)技术伺服跟踪外部控制信号以连续调节所需输出电流,这可确保开关管工作在近似零电流关断的状态下,开关损耗小,电源效率高。对该电源及其控制器原理进行了介绍,对DTM法进行了理论分析与研究,并通过Matlab仿真和实验验证了其原理的正确性和可行性。Based on the experimental physics and industrial control system(EPICS),a servo power controller is designed to be inserted into the existing power supply for testing its function of measurement and control in real time.The power supply controller uses dead time modulation(DTM)technology to adjust the output current by tracking the external control signal.Zero current switching(ZCS)can work under DTM,thus the switching loss can be reduced and the power efficiency can be greatly improved under high frequencies.In this paper,the principle of the power supply and its controller are introduced,and the DTM method is studied and verified by Matlab simulation and experiment for developing control technology of Tokamak power supplier.
