Computer-controlled opto-electronic power control system for three=phase AC machine

摘要

The computer controlled circuit includes three individual single-phase circuits (I,II,III), each with a load resistance user (1), a triac (2), a resistance (3,100-200 kohm), a Zener diode (4,50 V), a resistor (5, 200 ohm), a diac (6), a capacitor (8), a bridge rectifier and an optocoupler (9).
