Abstract

The invention discloses a pulse power supply for converting discharge by utilizing a three-winding pulse transformer. The pulse power supply comprises a high-voltage DC (Direct Current) power source, an energy storage capacitor, a controllable switch, a diode, a nonlinear resistor, a three-winding pulse transformer and a load. With the adoption of the structure, current in the same direction can be generated on the load no matter any change of the current of a primary winding, and residual current in the winding can be reduced rapidly by utilizing a voltage stabilizing function of the nonlinear resistor. Therefore, the pulse output time can be reduced greatly, and the energy conversion efficiency of the system can be improved.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to a large current generating device using a three-winding pulse transformer to convert and discharge, so as to improve the conversion efficiency of capacitor energy and reduce the time of pulse discharge. Background technique [0002] Pulse power technology is an emerging discipline that has developed rapidly in recent years. It slowly charges the energy storage device, and then quickly compresses and converts the energy in a short period of time to obtain various ideal peaks. The electric pulse output with high value and steep leading edge can provide strong current pulse power supply for various application devices. At present, the application fields of pulse power technology include not only particle beam weapons, pulse laser weapons, electromagnetic propulsion, and strong pulsed magnetic fields in the field of national defense scientific research, but also mecha...
