My circuit is a Wall-Wall rectifier circuit. The transformer is taking in 120Vac from the wall and stepping it down to 22Vac. A set of 4 diodew and a capacitor then supply 22 VDC with a ripple voltage of 50mV and a ripple frequency of 120Hz. Which diode should be purchased and why?

In the full-wave rectifier circuit of figure, the transformer has a turns ratio of 1:2. The transformer primary winding is connected across an AC source of 230V (rms), 50 Hz. The load resistor is 50ohms. For this circuit, determine the peak-to- peak ripple in the output voltage * Di i v2 = VmSin ot RL Vs(N V1 Vo + V3 = VmSin ot D2 Full-wave rectifier- Circuit operation during positive half cycle 460 V 207 V 325.3 V None of the above ell ell

You are an electrician working on an overhead crane. The crane uses a large electromagnet to pick up large metal pipes. The magnet must have a minimum of 200 VDC to operate properly. The crane has an AC source of 240 V. You are given four diodes that have a peak voltage rating of 400 V each. These diodes are to be used to form a bridge rectifier to convert the AC voltage into DC voltage. Is the voltage rating of the diodes sufficient? To the nearest volt, what will be the DC output voltage of the bridge rectifier?
