A step up chopper has input voltage 110 V and output voltage 150 V. The value of duty cycle is_____?
Correct answer: D. 0.27
- A. 0.32
- B. 0.67
- C. 0.45
- D. 0.27
Explanation
For an ideal step-up chopper, V_o=V_s/(1-D). Thus D=1-110/150=0.267, approximately 0.27; the larger duty-cycle values would produce much higher output voltage.
