NF93A-2 HESG440280R2 ABB | Power electronic module
Technical requirement
The gate shuts off the thyristor
High power thyristor (SCR) is almost the only semiconductor device that can withstand high voltage and high current in the past quite a long time. Therefore, in view of the disadvantages of SCR, it is natural for people to focus their efforts on how to make the thyristor have relevant breaking ability, and thus develop the gate break thyristor.
The GTO thyristor is used as the inverter to obtain satisfactory results, but the turn-off control is easy to fail, so it is still complicated and the working frequency is not high enough. Almost at the same time, the power transistor (GTR) was rapidly developed, making the GTO thyristor very similar. Therefore, in a large number of small and medium capacity frequency converters, GTO thyristor has been basically not used. However, because of its high working current, it still plays a major role in large capacity frequency converter.
