Project Title: Design a circuit which will give a fluctuating DC Output voltage for an Input Square Wave. Specifications: You will have a square wave as your source voltage where the square wave will have a Peak Amplitude of 24 V and Minimum Amplitude as 0 V with a frequency of 100 Hz. The output voltage is across a capacitor which will fluctuate. Besides, the driving voltage of the capacitor should be another square wave having a Peak Amplitude of 10 V and Minimum Amplitude as 0 V with the same frequency. The time constant is Ims. Now, design the whole circuit. Show the input/output graph in PSpice for the first 10 cycles. Submission Guidelines: One group should submit one simulation (.sch) file and one report (.pdf) file. The report must contain the following: 1. Cover Page 2. Objective (write the problem statement here) 3. Design (detailed calculation of values for all the selected components) (explain how you are getting the driving voltage of the capacitor from the source voltage.…
A step-down chopper is to be used to supply power from a 600-V overhead wire to the commutator motor on a trolley bus. The motor may be mod- eled as a generated direct voltage in series with a resistance of 0.2 and an inductance of 25 mH. The frequency of the chopper is set at 500 Hz.
