Question
n a certain application, a Half wave controlled rectifier is fed from a voltage vs(t)=320sin(100pi (t)) as shown in figure with an inductive load and a free-wheeling diode. The thyristor firing angle is 90 degrees. Therefore the average output voltage in Volts across the load is: Select one:a. 50.93b. 88.86c. 106.67d. 41.12
Solution
The average output voltage (Vavg) for a half-wave controlled rectifier with a firing angle (α) can be calculated using the following formula:
Vavg = (2Vm/π) * (1 + cosα)
Where:
- Vm is the peak voltage, which is 320V in this case.
- α is the firing angle, which is 90 degrees in this case.
Substituting the given values into the formula, we get:
Vavg = (2*320/π) * (1 + cos90) = (640/π) * (1 + 0) = 640/π = 203.64V
However, since it's a half-wave rectifier, we only get the output for half the input cycle. So, we divide the result by 2:
Vavg = 203.64/2 = 101.82V
