Answer #1

For a center tapped rectifier, where the center of transformer at the secondary turns is grounded has voltages of opposite polarities on both sides. Those opposite polarity voltages are to switch on only one of the diodes for each half cycle of the input. To observe those waveforms, both channels of the oscilloscope are needed.

    D *4.80 It is required to use a peak rectifier to design a de power supply that provides an average de output voltage of 12 V on which a maximum of ±1-V ripple is allowed. The rectifier feeds a load of 200 2. The rectifier is fed from the line voltage (120 V rms, 60 Hz) through a transformer. The diodes available have 0.7-V drop when conducting. If the designer opts for the half-wave circuit: (a) Specify the rms voltage...
