Given Information:
- RMS voltage across the inductor: 200 V
- Frequency: 50 Hz
- Output of DC-DC converter is always inverted
Calculating Duty Cycle:
The duty cycle of a DC-DC converter is defined as the ratio of time the switch is ON to the total time period. In this case, the output is inverted, meaning the switch is ON for half of the time period.
Given that the frequency of the square wave voltage across the inductor is 50 Hz, the time period T is calculated as:
T = 1/f = 1/50 = 0.02 seconds
Since the output is inverted, the switch is ON for half of the time period. Therefore, the duty cycle D is calculated as:
D = ON time / Total time = 0.01s / 0.02s = 0.5
Therefore, the duty cycle of the switch in this DC-DC converter is 0.5.
