Study on voltage limiting method for superconducting inductive pulsed power supply using nonlinear resistors
The approximate constant voltage characteristics of zinc oxide(ZnO)nonlinear resistors was utilized to limit the maximum voltage of the opening switch and primary superconducting winding.The influence of ZnO nonlinear resistance on the output characteristics of pulsed power supply circuits was simulated and analyzed,and a small-scale experimental platform was built to verify the principle of the proposed voltage limiting method.The simulation and experimental results show that the ZnO nonlinear resistor can significantly limit the voltage of the opening switch in the pulsed power supply circuit based on HTS pulse transformer.
