Control Strategies for Electrical Chopper
Q. List the control strategies used for chopper and explain TRC.
Q. State the working principle of chopper. State control techniques used for chopper.
Q. List the various control techniques used in chopper and explain any one technique in detail.
Q. State the application of chopper and list the various control techniques of chopper.
- For all the chopper configurations operating from a fixed dc input voltage V the average value of the output voltage VLdc is controlled by periodic opening and closing of the switches used in the chopper circuit.
- The average output voltage can be controlled by different techniques as explained as follows :
- Pulse Width Modulation (PWM) technique.
- Frequency modulation.
- Variable frequency, variable pulse width.
- CLC control.
