Pulsed power supply based on superconductivity normal-conductivity combined pulse transformer

Abstract

The invention discloses a pulsed power supply based on a superconductivity normal-conductivity combined pulse transformer, and the pulsed power supply is characterized in that a primary coil and a secondary coil of the superconductivity normal-conductivity combined pulse transformer adopt a different end serial-connection structure; when a power supply charging switch is closed, initial power supply charges a primary secondary coil in serial connection; and when the power supply charging switch is disconnected, partial energy in a primary superconductivity coil is transferred to a capacitor, and other energy is sensed to a secondary normal-conductivity coil through mutual inductance and then charges a load through the secondary normal-conductivity coil. After the transferring of the power is completed, the voltage of the capacitor reaches a maximal value, when a discharging switch is closed, and the load is discharged during the process that the capacitor charges the primary superconductivity coil in an opposite direction so as to complete the second pulse output. The pulsed power supply integrates the energy storage and discharging, large-current pulse can be outputted within a short time, and the pulsed power supply has advantages of small size, light weight and high energy conversion efficiency and has a promising application prospect and vast economic benefit.

AI Technical Summary

Problems solved by technology

[0004] Most of the traditional superconducting energy storage pulse power supplies are uncoupled energy storage inductors in series charge and parallel discharge mode. The pulse output in this mode needs to be realized by a circuit breaker, but the moment the energy storage inductor discharges, a high amplitude will be generated at both ends of the circuit breaker. The voltage pulse of the value is easy to cause damage to the circuit breaker, thus affecting the normal operation of the entire device

In addition, if you want to obtain higher amplitude current pulses, you need to stack many energy storage inductor modules. The more modules, the larger the system scale and the more complex the control system, which is not conducive to the miniaturization and lightweight application requirements of pulse power devices.
