Verified Answer
A step-up dc chopper has input dc voltage of 200 V and average output ...
Concept:
The output voltage of a step-up chopper is given by:
where,
Vo = Output voltage
VS = Input voltage
D = Duty cycle
The duty cycle (D) is
where,
TON = Conducting period or pulse width in seconds
TOFF = Non-conducting period in seconds.
T = Total conducting period = Pulse width.
T = TON + TOFF
Calculation:
Given
TON =150 μs
Vo = 500 V
VS = 200 V
T = 250 μs

Ms, what is the duty cycle of the chopper?
Duty cycle is defined as the ratio of the conduction time of the switch to the total time period.
Given:
Input DC voltage (Vin) = 200 V
Average output voltage (Vout) = 500 V
Conduction time of the switch = 150 ms
The duty cycle (D) can be calculated using the formula:
D = (T_on / T_total)
Where:
T_on = conduction time of the switch
T_total = total time period
Since the conduction time of the switch is given as 150 ms, we need to find the total time period.
The average output voltage can be expressed as:
Vout = D * Vin
Rearranging the equation to find D:
D = Vout / Vin
Substituting the given values:
D = 500 V / 200 V
D = 2.5
The duty cycle of the chopper is 2.5.
Duty cycle is defined as the ratio of the conduction time of the switch to the total time period.

The average output voltage can be expressed as:
Vout = D * Vin
Rearranging the equation to find D:

Substituting the given values:
D = 500 V / 200 V
D = 2.5
The duty cycle of the chopper is 2.5.
