Main directions of R&D for PPT

It related to R&D of:

new capacitor and induction energy storages;

new switches.

Capacitors:

New materials: solid, liquid for receiving of max electrical field.

Induction:

Switch

Perspective directions are next:

1. Semiconductor Open Switches- using forming of plasma in semiconductors, especially in SiC.

2. Vacuum switch with large cross section of cathode plasma. Reduction of induction of plasma channel (10-10 Henry).

Main task is low induction of switch channel.
