After debugging of the digital control system, we program a constant-current control software and make a power load experiment including external characteristic and dynamic characteristic tests on the almost the same conditions as that of simulation of Matlab model. 本文在完成对数字控制系统的调试后,按照前面设计的数字控制器进行了恒流控制软件编程,并在本文研制的数字化弧焊逆变电源上进行了功率负载试验,实现了恒流闭环控制。
Furthermore, the precise time when the constant-current characteristic changes and the voltage on the load capacitor at that moment are calculated. 此外还计算出了恒流特性发生变化的时刻以及该时刻对应的负载电容电压。
