大功率高稳定度恒定电源的控制方式大体可分两种类型,一种是采用运算放大器闭环控制,另一种是全可控硅控制方案.当采用这两种控制方案时,设备一经调试完毕,其控制方式及运行方式是无法更动的.采用微计算机控制大功率高稳定度电源方案,其立足点在于用软件代替硬件线路.利用软件可以实现PID调节或PD调节,这样有利于提高系统的稳态精度,同时也改善了系统的动态特性.引入微计算机控制以后,用户可以将所需的程序固化在EPROM中,从而方便地实现系统的闭环控制及采集负载参数等功
High-power high-stability constant power control can be broadly divided into two types, one is the use of operational amplifier closed-loop control, the other is full SCR control program.When using these two control programs, the device has been commissioned , Its control mode and mode of operation is unable to change the use of micro-computer control high-power high-stability power scheme, the foothold is to use software instead of hardware lines. Software can be used to achieve PID regulation or PD regulation, which will help improve the system Of the steady-state accuracy, but also improve the dynamic characteristics of the system.After the introduction of microcomputer control, the user can cure the required programs in the EPROM, so as to facilitate the system’s closed-loop control and acquisition of load parameters such as power
