Gate-Treiber für Thyristor

A predetermined signal pattern is generated to produce current for driving the GCT thyristor. The current is produced by the use of a down converter. Also, a current limiter having an FET is used for protecting the down converter from being damaged by a negative voltage appearing at the gate of GCT...

Zusammenfassung:	A predetermined signal pattern is generated to produce current for driving the GCT thyristor. The current is produced by the use of a down converter. Also, a current limiter having an FET is used for protecting the down converter from being damaged by a negative voltage appearing at the gate of GCT when the GCT thyristor receives reverse direction load current.
