NEETPhysicsSemiconductors
In a center-tap full-wave rectifier circuit using ideal diodes, the alternating voltage between the center tap and either end of the secondary coil has a peak value of V₀ . What is the maximum reverse voltage (Peak Inverse Voltage) that appears across any one of the diodes during its non-conducting state?
Options
- AV₀
- BV₀ 2
- CV₀ 2
- D2V₀
Correct answer
D. 2V₀
Step-by-step solution
In a center-tap full-wave rectifier, the secondary coil is divided into two halves by the center tap. The peak voltage of each half is given as V₀ . During a half-cycle when one diode is forward-biased and conducting, it acts as a short circuit (for an ideal diode). This connects the common cathode terminal to the peak positive voltage V₀ of one end of the secondary coil. At this same instant, the other end of the secondary coil is at a peak negative voltage of -V₀ with respect to the center tap. The non-conducting
