  • Bi-level Control and Chopper Control Methods for Improving .

    CiteSeerX - Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): This paper compares between chopper control method and bi-level control method. Both methods are used for improving the dynamic performance of variable reluctance stepper motor (VRSM) by modifying its time constant and thus, increasing its stepping rate. Therefore, the initial torque developed by the motor is high .

    justifiable improvement is the "Bi-Level-Drive" (fgi . 9). Thsi circuit concept works with two supply vol-tages ; with every new step of the motor both win-dings are connected for a short time to a high supply voltage. This considerably increases the current rate of change and its behaviour corresponds more or less to the stabilized power .

  • Chopper (electronics) - Wikipedia

    In electronics, a chopper circuit is used to refer to numerous types of electronic switching devices and circuits used in power control and signal applications. A chopper is a device that converts fixed DC input to a variable DC output voltage directly. Essentially, a chopper is an electronic switch that is used to interrupt one signal under the control of another.

  • Stepper motor - Wikipedia

    Stepper motor performance is strongly dependent on the driver circuit. Torque curves may be extended to greater speeds if the stator poles can be reversed more quickly, the limiting factor being a combination of the winding inductance. To overcome the inductance and switch the windings quickly, one must increase the drive voltage.
