Pulsed power solutions

Pulsed power solutions up to 100 kV and several hundreds of kA

Pulsed power is a technology that focuses on delivering high-energy electrical pulses. This technology plays a crucial role in enabling applications that require the generation of extreme powers for short periods of time at high repitition. Astrol pulsed power solutions are based on thyristors, high di/dt-thyristors, IGCTs, Hipak IGBTs, Stakpak IGBTs, Linpak IGBTs, and designed to switch store and release energy rapidly.

The design and engineering of these systems are highly complex, as they need to manage high voltages and currents while maintaining safety and reliability. In the light of this complexity, Astrol is expert in designing and manufacturing high-quality pulsed power solutions of upto 100 kV and several hundreds of kA.
