Question Description
Design a dc Power supply circuit that will provide a regulated voltage of about 10 V from an AC linevoltage of 120 V r.m.s (the voltage you get from the wall outlet). The load current in the desired dcpower supply circuit can vary from 0 mA to 20 mA and the regulated output voltage can vary atmost ±1% of the desired output, 10V.To meet the desired specification, you are suggested to use a peak rectifier circuit (consists of abridge rectifier and a capacitor) that allows a maximum ripple of ±1V. The rectifier feeds aresistance of 150 Ω (as shown in the figure, next page). Note that the rectifier is fed from the linevoltage (120 V rms, 60 Hz) through a 10-to-1 step down transformer. The diodes available have 0.7-V drop when conducting. The output of the peak rectifier is connected to the input of the voltageregulator to produce the desired regulated voltage of about 10V.For voltage regulation, the available Zener diode is specified to have a Vz = 10V at a test current of25 mA. The other parameters provided by the manufacturer are rz =10 Ω and IZK = 2.5 mA.Show all the detailed calculations of your design. In particular,For peak rectifier- Find the value of the dc output voltage of the rectifier filter and the requiredvalue of filter capacitor that supports the desired ripple, also find the maximum reverse voltage thatwill appear across the diode, and specify the PIV rating of the diodes, Calculate the average currentthrough the diode during conduction, Calculate the peak diode current.For regulator- Calculate the required value of R, Find the load regulation. By what percentage doesVO change from the no-load to the full-load condition? Check whether the change in output voltagemeets the desired specification (use Multisim to verify your calculation). Find maximum powerdissipation in the Zener diode.Do the simulation using Multisim and show that the required specifications are met.Use Cursor to measure the output voltages in each section, also measure the ripples to justify yourclaim. Show that under different loading conditions the output voltage is within the desired rangementioned in the specification. Take snap-shot of each measurement and submit it with the projectreport.
