Toshiba Electronic Devices & Storage Corporation has introduced the 6500V/2000A press pack IEGT “ST2000JXH35A,” featuring newly developed trench-type IEGT chips designed for high-voltage converter applications such as DC power transmission systems, industrial motor drives, and STATCOM installations.

As renewable energy sources including wind, solar, and hydro power continue expanding to combat global warming, power generation sites are increasingly located far from major consumption areas. This trend is driving demand for long-distance transmission solutions.

High-voltage direct current (HVDC) systems are gaining traction due to their:

  • Lower transmission losses over long distances
  • Improved controllability compared to AC systems
  • Enhanced ability to manage renewable output fluctuations

The ST2000JXH35A is designed to support these evolving grid requirements.

The newly developed trench-type IEGT chips feature an optimized cell structure that delivers:

  • High turn-off capability
  • High short-circuit withstand capability

The device has successfully passed both turn-off and short-circuit testing at a test voltage of 4500V, validating its suitability for demanding high-voltage environments.

By adopting the 6500V-rated ST2000JXH35A, system designers can reduce the number of series-connected devices in DC transmission systems by approximately 33% compared to 4500V-rated configurations.

This reduction enables:

  • Lower system weight
  • Smaller overall equipment footprint
  • Reduced construction and transportation costs

These advantages are particularly significant for offshore converter stations, where logistics and structural costs are high.

Beyond DC power transmission, the ST2000JXH35A supports higher voltage and more compact designs in:

  • Industrial motor-drive equipment
  • STATCOM (Static Synchronous Compensator) systems

Toshiba stated it will continue developing press pack IEGTs for high-voltage converters and plans to further expand its product lineup to address the growing needs of energy infrastructure and industrial power systems.
