摘要： An AC power controller system applies three-phase AC operating power to an induction motor that drives a non-linear mechanical load. A primary low pass filter is connected in series between branch phase conductors and a power controller of the type that uses gate-controlled switching thyristors for controlling power to the motor. KVAR capacitors connected between the power controller and the induction motor phase windings form a secondary low pass filter across the controller output terminals. The primary and secondary low pass filters isolate the power controller and induction motor with respect to spurious noise and harmonics generated by local as well as remote sources, and also improve real power transfer efficiency from the power generating source to the induction motor by transforming the effective impedance of the power source and induction motor load.

摘要： An AC induction motor is controlled by dynamically matching energy use by the motor to the load on the motor. First and second SCRs are connected in parallel with each other in opposing polarities for each phase of the applied AC voltage. A trigger generator couples trigger control signals to the respective gates of the SCRs responsive to the timing of sensed zero-crossing events of the AC voltage and current in the respective phase applied to the motor winding. The first and second SCRs are alternately triggered into a conductive state during each alternation of the applied AC voltage and are alternately inhibited from the conductive state for an interval in time proportional to a measured difference in time between the AC voltage zero-crossing and the corresponding AC current zero-crossing as determined by comparing the time difference between successive first and second interrupts corresponding to the zero-crossing events with a continuously running time base.
