New Press Pack IEGT That Contributes to Size Reduction and Higher Output for High-Voltage Converters Such as DC Power Transmission Systems and Industrial Motor Controller

Product News 2024-02

The package photograph of new press pack IEGT that contributes to size reduction and higher output for high-voltage converters such as DC power transmission systems and industrial motor controller.

Toshiba Electronic Devices & Storage Corporation (“Toshiba”) has launched a newly developed press pack IEGT[1] "ST3000GXH35A” with ratings of 4500 V/3000 A for use in high-voltage converters.

The new product ST3000GXH35A has optimized N buffer layer design, thereby reducing approximately 400 V[2] of turn-off-voltage oscillation peak-value (Vcp[3]) at low current, compared with the Toshiba’s existing product[4]. This helps simplify the snubber circuit.
In addition, the measuring voltage of short-circuit pulse-width has been enhanced to 3400 V[5] in response to applications requiring high voltage.
This allows facilitating the short-circuit protection design of converters.
