Main directions of R&D for PPT
1. Production of max power in pulse.
2. Transfer to short pulses duration
(picoseconds, femtoseconds).
5
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:
Superconductors: High Temperature Superconductors.

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.

Industrial products
Marx generators with pulse duration from 20
ns to till 100 microseconds.
Induction generators with pulse duration from
1 ns to till 1,0 microseconds..
Fast switches ( 5-20 nsec rise time).
High current pulsed switches for converters.
Diagnostics: High voltage probes, current
transformers.
