If T is the chopping period, Ton the on-time period of chopper and Tof...
Answer:
Introduction:
A chopper is an electronic device used to control the output voltage of a DC power supply by varying the duty cycle of a rectangular waveform. The duty cycle is defined as the ratio of Ton (on-time period of the chopper) to the chopping period T. There are different methods of controlling the output voltage of a chopper, including pulse-width modulation (PWM) and variable-frequency modulation (VFM).
Explanation:
Let's analyze each statement one by one:
Statement 1: In pulse-width modulation (PWM) scheme, T is kept constant while Ton is varied.
This statement is correct. In PWM scheme, the chopping period T is kept constant while the on-time period Ton is varied to control the output voltage. By varying the Ton, the average value of the output voltage can be adjusted.
Statement 2: In variable-frequency modulation (VFM) scheme, T is varied while either of Ton or Toff is kept constant.
This statement is correct. In VFM scheme, the chopping period T is varied while either the on-time period Ton or the off-time period Toff is kept constant. This allows for control of the output voltage by adjusting the chopping frequency.
Statement 3: In PWM scheme, the output voltage can be varied between zero to source voltage.
This statement is correct. In PWM scheme, by varying the Ton, the average value of the output voltage can be adjusted. It can be varied between zero and the source voltage by adjusting the duty cycle.
Statement 4: The large Toff in VFM scheme may make the load current discontinuous.
This statement is correct. In VFM scheme, if the off-time period Toff is large, it may result in a discontinuous load current. This can cause additional ripple and distortion in the output voltage waveform.
Statement 5: PWM scheme is better than VFM scheme.
This statement is correct. PWM scheme offers better control and accuracy of the output voltage compared to VFM scheme. By adjusting the duty cycle, the PWM scheme allows for precise control of the output voltage, whereas in VFM scheme, control is achieved by adjusting the chopping frequency.
Conclusion:
Based on the analysis of each statement, we can conclude that all the statements - 1, 2, 3, 4, and 5 - are correct.
