A 200-V, 3-A dc power supply is to be designed with less than a 2 percent ripple voltage. Compare the pros and cons of implementing this power sup- ply with half-wave, full-wave, and full-wave bridge rectifiers. 200-V, 3-A power supply with V, ≤4 V. Assume Von = 1 V. Rectifier Type Peak Current PIV Filter Capacitor 12,500 μF 6250 µF 6250 µF (i) The the half-wave rectifier requires a larger value of C which may lead to more cost. (ii) The PIV ratings are all low enough that they do not indicate a preference for one circuit over another. Half Wave 189 A 402 V Full Wave 94.3 A 402 V Full Wave Bridge 94.3 A 202 V (iii) The peak current values are lower for the full-wave and full-wave bridge rectifiers and also indicate an advantage for these circuits. (iv) We must choose between use of a center-tapped transformer (full-wave) or two extra diodes (bridge). At a current of 3 A, the diodes are not expensive and a four-diode bridge should be easily found. The final choice would be made based upon cost of available components. - A 200-V, 3-A dc power supply is to be designed with less than a 2 percent ripple voltage.
