Question
A half wave rectifier has a 200 V rms. source and the step-down transformer has a turns ratioof41.What will be the peak voltage across the load ignoring thedrop acioss the diode?
Solution
The peak voltage across the load can be calculated using the formula for the peak voltage of a sinusoidal waveform, which is Vpeak = Vrms * sqrt(2). However, since there is a step-down transformer involved, we need to take into account the turns ratio of the transformer.
Here are the steps to calculate the peak voltage across the load:
-
Calculate the peak voltage of the source: Vpeak_source = Vrms_source * sqrt(2) = 200V * sqrt(2) = 282.84V
-
Calculate the peak voltage across the transformer: Vpeak_transformer = Vpeak_source / turns ratio = 282.84V / 4 = 70.71V
-
Since we are ignoring the drop across the diode, the peak voltage across the load is the same as the peak voltage across the transformer, which is 70.71V.
