Study on the Application of SIMADYN D Controller in High-power Arc Heater

DC supply,which uses thyristor to regulate voltage,has faster dynamic response characteristic than the supply using saturated-reactor.Moreover the former has higher control precision than the later due to the adoption of closed-loop thyristor current control.The application of SIMADYN D controller was deeply researched.The controller,with which the voltage stabilizer,current stabilizer and sequential control strategy are realized,was used to control a high-power arc heater.Experimental results show that the controller is of perfect performance and runs reliably,and can fulfill the requirement of the arc heater control.
