Electrical switch capacitive energy storage

What is a capacitive energy storage system?

This capacitive energy storage includes the capacitor cells of 200 kJ stored energy, each incorporating one self-healing high-energy-density capacitor, one semiconducting switch unit on the basis of Light Triggered Thyristors (LTT) and the pulse diodes, as well as the toroid inductor.

Which semiconductor switches are suitable for capacitive energy storage?

For capacitive energy storages with the discharge process lasting fractions of milliseconds or several milliseconds the most suitable are semiconductor switches built on Light Triggered Thyristors (LTT) [1, 2].

What is capacitive switch technology?

Capacitive switch technology is a proven upgrade to mechanical controls in electronic user interfaces, according to Steve Fulton, engineering manager at Molex. This technology offers enhanced functionality, exceptional product reliability, and energy savings.

Can capacitive energy storage be used in laboratory conditions?

The conceptual design of the capacitive energy storage intended for operation in laboratory conditions is considered.

Can crowbar diodes switch a capacitive energy storage unit?

The design of the switch unit for the capacitive energy storage comprising LTTs and crowbar diodes is described, and the transient processes of current switching in crowbar diodes are considered. The tests carried out during switching of pu1se current up to 100 kA at a voltage of 6 kV have confirmed the workability of the switch unit. 1.

What happens when a capacitor cell is discharged in short-circuit mode?

When the capacitor cell is discharged in the short-circuit mode, the current pulse amplitude and duration are maximal. Therefore, this mode is the most severe for discharge switches of capacitive energy storage.
