Direction and Speed Control of DC Motors using Dual Converter

A bidirectional power electronic device controls the direction and speed of DC motors when they are operated with a dual converter.

Direction Control

  • The dual converter’s capacity to produce bidirectional power flow allows the DC motor’s current to be reversed.
  • The direction of the DC motor can be easily changed by varying the firing angle of the thyristors.

Speed Control

  • Dual converters allow variable speed control by altering the thyristors’ firing angles.
  • This speed can be changed without any external mechanical component.
  • A higher angle of fire results in higher voltage to the motor, which increases its speed.
  • When the firing angle decreases, the motor speed decreases along with the voltage.

Bidirectional Power Flow

  • The dual converter is especially appropriate for applications requiring fast changes in motor speed and direction because of its capacity for bidirectional energy flow.

Smooth Control

  • Precise control of the firing angles allows smooth, continuous adjustments that enable accurate control over the motor’s direction and speed.
