A SYSTEM AND METHOD FOR INCREASING THE EFFICIENCY OF ALTERNATING CURRENT INDUCTION MOTORS. |
摘要 |
A system for increasing the efficiency of single and multi-phase induction motors. The system is comprised of a microcontroller which combines a time when the AC line current reaches zero amps with a time when AC line voltage to the AC motor reaches zero volts and with a digital measurement provided by an A/D converter to determine a servo error. The servo error determines whether the A/C motor needs more or less power. The microprocessor provides a control signal to a switching means to supply the minimum power required based on the servo error. |
