For the step-down chopper shown in the figure below, dc source voltage = 230 V. Find the power input to the chopper If load of R = 10 Ω is connected. Duty cycle = 40 %.

For the step-down chopper shown in the figure below, dc source voltage = 230 V. Find the power input to the chopper If load of R = 10 Ω is connected. Duty cycle = 40 %. Correct Answer 2097 W

Power input to the chopper is Vs . Io Vs = 230 V Vo = (Vs – 2) x Duty cycle = 91.2 V Io = Vo/R = 91.2/10 Pi = Vs.Io = 2097.6 W.

Which of the following statements are correct for an ideal constant voltage source? 1. Its output voltage remains absolutely constant whatever the change in load current. 2. It possesses zero internal resistance so that internal voltage drop in the source is zero. 3. Output voltage is provided by the source would remain constant irrespective of the amount of current drawn from it. 4. Output voltage provided by the source varies with the amount of current drawn from it.
In the above figure, the load voltage is positive whereas the load current is negative. Thus, the current flows out of the load and into the source. Identify the type of chopper shown in the figure.
