Capacitor energy storage applications related to pulse field

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 is a capacitor-based pulsed power supply (PPS)?

What’s this? Capacitor-based pulsed power supply (PPS) is widely used in fields related to electromagnetic launch, plasma, and materials' synthesis, modification and processing.

Is BKT-BST-CT a suitable material for energy storage capacitors?

Furthermore, the ceramic has brilliant charge–discharge characteristics with a rapid discharge rate (t0.9 < 90 ns), a large current density (1151 A/cm 2), and a superpower density (143.9 MW/cm 3). The obtained findings indicate that the designed BKT-BST-CT specimen may be a prospective material for energy storage capacitor applications.

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.

What is a lead-free relaxor ceramic capacitor?

Environmentally friendly lead-free relaxor ferroelectric ceramic capacitors with high energy density at moderate electric fields are critical for many pulse power systems. However, their moderate field energy storage property is usually restricted greatly by the limited polarization difference of the dielectric ceramic.

Can ceramic compounds be used as pulse power capacitors?

Owing to the higher polarization under low field than most of the reported compounds, the 0.93NBT-0.07LA ceramic possesses an ultra-high W d under low field compared with other bulk ceramics. Therefore, these ceramic compounds could be potentially applied as pulse power capacitors. Fig. 6.
