1 Determine the peak output voltage for the bridge rectifier in Figure 1 shown. Assuming the practical model, what PIV rating is required for the diodes? The transformer is specified to have a 12 Vrms secondary voltage for the standard 120 V across the primary.

Figure 1. Bridge Full Wave Rectifier

2 In the full-wave center-tapped rectifier circuit, 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 50?. For this circuit, determine the DC output voltage, peak-to-peak ripple in the output voltage, and output ripple frequency. Show all work.
