Item Details

This is a modular programmable high-current pulsed power supply capable of delivering a current of up to 700,000 Amperes. The system is a switched capacitor-discharge pulse-forming network (PFN). There are 32 thyristor-switched capacitive modules that can each be individually controlled to deliver 32kA each, and 4 modules capable of delivering 45kA each. The system comes with voltage dividers and a relay network with resistors for safe discharging
Modules can also be separated into custom combinations or operated individually for various other applications.

1x cabinet contains
16x Type 1 modules, each module has:
400V rated capacitor bank, 1.6kJ energy storage per module
150A/us rate of rise for current
30kA peak short circuit current
1200V rated thyristor and two diodes in semiconductor clamp assembly
 2.2uH pulse power inductor with 500 microOhm ESR, rated for 30kA
Ultra fast gate drive units for each module
Fully independent control
4x Type 2 modules
