TCA 785

Fully Controlled AC Power Controller

Circuit for Two High-Power Thyristors

Shown is the possibility to trigger two antiparalleled thyristors with one IC TCA 785. The trigger

pulse can be shifted continuously within a phase angle between 0˚ and 180˚ by means of a

potentiometer. During the negative line half-wave the trigger pulse of pin 14 is fed to the

relevant thyristor via a trigger pulse transformer. During the positive line half-wave, the gate of

the second thyristor is triggered by a trigger pulse transformer at pin 15.
