What is a pulsed power supply?

As industrial applications place higher requirements on compact and portable pulsed power supplies, the National Key Laboratory of Transient Physics (NKLTP) recently developed a pulsed power supply consisting of a set of compact pulse-forming units (PFU), each with a capacitor energy storage of 220 kJ.

How do pulsed power devices store energy?

There are a variety of ways for the primary energy of the pulsed power devices to store energy. Capacitors carry out the storage in the form of electric fields, while inductors, mechanical energy generators, chemical energy devices and nuclear energy devices achieve the goal by magnetic fields.

What is a high-power pulsed power supply?

The high-power pulsed power supply is the power supply that provides electromagnetic energy to the pulsed power devices. It constitutes the main body of the pulsed power device, as in almost all parts of the pulsed power device are included.

What are the components of a pulsed power supply?

The pulsed power supply consists of an adjustable DC voltage power supply, E1, a filtering current-limiting inductance, L1, a resonant energy storage capacitor, C1, a feedback diode, DT, of the fast switching thyristor, D1, and a resonant circuit L2 which composes of resonant inductors.

What is a capacitive pulsed power supply?

Capacitive pulsed power supply is considered one of the most stable and reliable energy source for electromagnetic launcher. Several PFUs are connected in parallel to form a pulse forming network (PFN), with each module operating in a sequential discharge mode.

What are the technical problems of high-power pulsed power supply?

The core technical problem of high-power pulsed power supply is pulsed- power energy storage system with high energy storage density (kJ/kg) and high- power density (kW/kg). It requires good controllability and small internal resistance of the pulsed discharge waveform to fulfill the needs of different loads.
