SYSTEM AND METHOD FOR AUTOMATIC CURRENT LIMIT CONTROL |
摘要 |
A motor controller system comprises solid state switches for connection between an AC line and motor terminals for controlling application of AC power to the motor. A sensor senses AC line voltage. A control circuit controls operation of the solid state switches. The control circuit ramps switch current during a start mode and selectively holds switch current during the start mode if sensed voltage drops below a threshold amount.
