CONTROL CIRCUIT FOR POWER CONTROL BY MEANS OF A THYRISTOR

摘要

The invention concerns the use of a thyristor in a control circuit for electric power control. The thyristor is so connected and controlled that the number of complete half cycles during which the thyristor is conductive and non-conductive is varied, the thyristor being rendered conductive by a control pulse at its gate electrode immediately before or at the start of the half cycles during which the thyristor is to be conductive.
