Achievement of digital control technology on high-power silicon controlled rectifier

摘要：

To fulfill the need of experimental DC supply of subway inverter, this paper designs and develops a set of rectifier system of 160kW, output voltage can be adjusted from 500V to 900V. This article uses SCR as main switches, the trigger circuit adopts digital trigger circuit, the control of whole system is achieved by DSP. The main control method is digital PI, which used to control the output DC voltage to be dynamically stable. The main circuit parameters and control method are simulated by MATLAB/Simulink. The results validate the system design.
