Assemblies for high power applications

Hitachi Energy designs and produces complete solid-state assemblies, including the semiconductor device, driving circuit, triggering, mechanical clamping, cooling, and application-specific testing.

Hitachi Energy offers assemblies for applications in various environments like research & development, laboratory and production.

The semiconductor devices are designed to switch very high current rise rates (di/dt) for Pulse Power applications. They feature fast turn-on, very high current and high voltage blocking capability.

Due to higher reliability and lower maintenance costs, Hitachi Energy's optimized assemblies are increasingly replacing thyratrons and ignitrons.

We offer assemblies covering the range of voltage up to 120 kV and current up to 200 kA using series and parallel connections. Custom build assemblies are available on request.
