Active Trigger Units for Thyristors

The Active Trigger is an economic replacement of

pulse transformers including all associated circuitry in

phase controlled thyristor equipment. Due to the small

control current it becomes the ideal link between any

size of thyristor and the control intelligence. Each

Active Trigger can trigger two thyristors and is

intended for mains voltages from 115V to 690Vrms.

Its operation is based on an optically activated current

source connected between anode and gate of the

thyristor to be triggered. Thus a small electrically

isolated control current initiates a large gate current

without the necessity of a gate drive power supply.

Three different application specific types are

available.

PSTT PC - controlled rectifiers, ac controllers, dc motor control, all other applications

PSTT SC - economic low cost ac controllers

PSTT ZC - zero crossing switching – heating, welding, power factor correction
