Calculate the following for a load resistance of 25 ? and a smoothing capacitance of 1000 µF: rms and peak voltage across the secondary winding of the transformer the peak voltage across the capacitor the peak-to-peak and rms ripple voltages the load d.c. voltage and current. Model the power supply circuit using PSPICE and use the simulation to plot the load and ripple voltages, the current in the capacitor and a diode. Compare the waveforms with the values calculated above and attempt to account for any discrepancies. Briefly explain the function and operation of TR1, TR2, R1 and R1 in the circuit shown in FIGURE 2. R2 TR1 Created with an evaluation copy of Aspose.Words.
