High Voltage Switch Module

EHT High Voltage Switch (HVS) Modules consist of a series and/or parallel arrangement of solid-state switches with integrated fiber optic trigger, precision gate drive, and fast energy storage. Using an EHT HVS module eliminates the challenges typically associated with series stacking including voltage sharing, thermal balancing, triggering. This allows the user to focus on power system development.

Low Current HVS (< 200 A)

Features

  • Easily stacked in series for higher voltage operation
  • Fiber optically isolated gate power for fast switching
  • Built-in overcurrent and overvoltage protection
  • Optional corona bars for higher voltage stacks
  • Optional heat sinking for continuous high-power operation

Specifications

  • Max operating voltage: 10 kV
  • Max operating current (pulse width dependent): 200 A at 5μs
  • Rise time: 70 ns
  • Adjustable pulse width - flattop depends on capacitor bank
  • Adjustable pulse repetition frequency - depends on included thermal management
