System Power Factor Control for AC Induction Motors.

摘要

System Power Factor Control for AC Induction Motors.It consists of a triac (22) connected in series with the motor (10) is shot in the controlled portions of each half cycle of the Input Voltage; a low value resistor (24) Connected In Series, which serves to develop a sen / proportional to current flow through a (10); Potentiometer (78) to provide sen / output error to Zero; a Processor (18) derIvacion (32) in its Secondary Trainers (34, 36), square wave and Sawtooth (42, 44); a multiplier (48); an isolation Transformer (52); a square wave pulse Shaper (54); a differentiator (58); a Shot (62); an Integrator (66); and an Operational Amplifier (70).
