Date of allocation : 31/03/2013 Date of submission : 07/04/2013 Submitted To : Student’s ID : 2013-1-80-022 Student’s Name : Md. Solayman Khan Mariam B. Salim Objective: In this experiment we performed DC analysis of circuits by sweeping DC sources and resistances.We also used the application of resistance sweep to study maximum power transform theorem. Answer to the que no : 1 The signed printouts of the print-outs of the PSPICE simulation results are attatched after this page. Answer to the que no : 2 Comparison of the theoretical sollutions with the PSPICE obtained sollution is given below: VOC(v) ISC(mA) VTh(v) RTh(Ω) V(3)(v) V(5)(mV) I(R5)(mA) PMax(mW) Type Calculated 1.875 176.5 1.875 10.62 1.818 909 90.9 82.8 PSPICE 1.875 176.5 1.875 10.63 1.818 909 90.9 82.721 Answer to the que no : 3 There are some possible applications of DC sweep.They are voltage source sweep,temperature sweep,current source sweep,parameter value sweep etc. DC voltage source sweep is useful to determine node voltages with the change of time. DC resistance sweep is useful to determine thevenin’s equivallent resistance using maximum power transfer theorem. Answer to the que no : 4 Maximum power transform theorem can be used to determine the Thevenin’s equivalent resistance of a circuit. According to the maximum power transform theorem,maximum power will be transformed to load resistance when the load resistance is equal to the thevenin’s equivalent resistance between the two nodes of load resistance.Using this theorem,we can determine thevenin’s equivalent resistance.To do this,we have to see ,for which value of the load resistance,we are getting the maximum power.And that value will be the value of thevenin’s equivallent resistance. Conclution : In this experiment, we performed DC analysis of circuits by sweeping DC source and resistance.We also studied maximum power transform theorem by using the application of resistance sweep.Now ,we can obtain thevenin’s equivallent resistance by using maximum power transform theorem by resistance sweeping.
