Bipolar Thyristor - Pulse Power Thyristors

Pulse Power Thyristor

Dynex Pulse Power Thyristor Switches are used for continuous power control and are specifically engineered for extreme high-current, high-energy discharge events with very fast current rise.

They are used in systems requiring controlled, high-energy discharge pulses, including:

• Replacement of gas-based switches (e.g. thyratrons, spark gaps, ignitrons) in pulsed power laboratories
• Fusion research, such as Tokamak systems
• Particle accelerators
• Magnetic pulse welding and metal forming
• Rock fracturing and plasma drilling
• Defence and specialist systems, including electromagnetic launch and laser systems
• Medical systems such as pulsed X-ray generators and pulsed radiation equipment

In pulse-power applications, success is not only about switching, but about controlling energy at scale with precision, robustness, and repeatability.

Pulse Power Thyristor Key Features

• Very high di/dt capability, typically above 2 kA/µs and in some cases exceeding 20 kA/µs, enabling rapid current rise without localised thermal failure
• Low on-state losses for efficient transfer of stored energy
• Robust junction design to withstand repetitive pulsed operation
• High surge current capability to handle extreme peak currents
• Strong dV/dt capability for reliable blocking performance
• Long operational life in repetitive pulse environments
• Blocking voltage range typically from 3.3 kV to 8.3 kV
• Available in both symmetric and asymmetric blocking types
• Can be integrated into higher-power and voltage stack assemblies by Dynex Power Assemblies team
• Low timing jitter for precise and repeatable pulse delivery
