基于超导脉冲变压器的脉冲电源不同限压方法
Different voltage limiting methods of pulse power supply based on superconducting pulse transformer
摘要
Abstract
Inductive energy storage is one of the main energy storage methods of pulse power technology,and the problem of limiting voltage of open circuit switch is its inherent problem.To explore the voltage limiting method of superconducting pulse power supply,this paper introduces two traditional voltage limiting methods,namely ZnO varistor voltage limiting and pulse capacitor voltage limiting,and puts forward the combination of pulse capacitor and varistor to limit the open switching voltage.The working principle of superconducting pulse power supply under three voltage limiting modes is analyzed,and the output characteristics under different voltage limiting parameters are simulated based on the same superconducting pulse transformer parameters.Aiming at the combined voltage limiting mode,a small experimental platform was built to verify the voltage limiting performance of the device.Simulation and experimental results show that the combined voltage limiting mode has higher transmission efficiency and better turn-off performance than varistor,and it has faster discharge and lower voltage amplitude than pulse capacitance limiting mode.关键词
