WEBVTT 00:00.900 --> 00:09.450 Hello, so I had a few changes, which I need to tell you guys, so in the voltage source here, you 00:09.450 --> 00:12.970 have to write if I you and not a 40 kilohertz. 00:12.990 --> 00:13.320 OK. 00:14.730 --> 00:22.810 We are running just in 25 years, and I have set up for you as 25. 00:22.830 --> 00:26.250 OK, just make this correction when you were running the simulation. 00:26.520 --> 00:34.860 So if you are curious, 25 in the field this year, it will just be if our Q and R one is said, two 00:34.860 --> 00:37.980 hundred homes and our two thousand homes. 00:38.180 --> 00:41.520 OK, now how to run the simulation. 00:41.860 --> 00:47.220 We have to first go to study and then and we have to click on and study. 00:47.760 --> 00:51.800 When you click on our study you will get these options just right. 00:51.810 --> 00:55.920 Click on time dependent study and click on and study. 00:57.070 --> 00:59.420 Now it will be added a new model builder. 01:00.130 --> 01:08.140 What you need to do is we will study in the millisecond domain, so we'll select millisecond and we 01:08.140 --> 01:17.810 will run in the step of zero point five millisecond up to, let's say, five hundred milliseconds. 01:18.340 --> 01:19.780 There is no hard and fast rule. 01:19.780 --> 01:28.390 You can play with your time and to compute the need to click, study and then click on compute. 01:28.810 --> 01:34.060 Once you click on compute, it will take four seconds to run the simulation depending on the number 01:34.060 --> 01:37.850 of components and the simulation is complete. 01:38.770 --> 01:44.330 So how to check the results now to plug the results? 01:45.430 --> 01:52.990 At first we will try to plot the voltage of the voltage source, whether it looks like an AC source 01:52.990 --> 01:55.120 and not to do that right. 01:55.120 --> 01:56.140 Click in the results. 01:56.980 --> 01:58.870 Click on one deployment group. 02:01.090 --> 02:06.650 When you click on one deployed group, you need to add a global plot to do that. 02:07.180 --> 02:09.850 Go on and click on Global Plot. 02:11.360 --> 02:20.720 Now click on the expression and here in the air, the expression, open up electric circuit devices, 02:21.290 --> 02:29.540 click on V one and then select voltage across V1, which is basically the voltage across your will, 02:29.590 --> 02:33.170 the source, then double click on it and it will be added. 02:33.620 --> 02:41.480 Now from the data set parent, you can select solution one or you can select parent doesn't matter much. 02:42.140 --> 02:43.640 Now click on Plott. 02:44.360 --> 02:52.590 When you click on Plott you will see there is a nice AC voltage which you can see in the plot. 02:53.840 --> 02:57.650 Now let's say I want to plot the voltage across. 02:57.720 --> 03:01.490 It is there are one, remember in a full way rectifier. 03:01.490 --> 03:08.420 The voltage across that is there is actually the positive, uh, slope's. 03:08.420 --> 03:13.790 So we should get the positive curves and not the negative curves. 03:14.330 --> 03:22.760 So I'll click on add expression and go again to the circuit devices are one and then double click on 03:22.760 --> 03:33.500 voltage across device one now and I click on Plott you will see that we have the voltage uh across the 03:33.500 --> 03:36.140 register which is in the negative side. 03:36.350 --> 03:38.510 So basically the polarities are different. 03:38.780 --> 03:44.330 And to put it in the positive perspective, I can just put a minus sign on. 03:44.330 --> 03:48.380 What you can do is in the register you can change three and four to four and three. 03:48.680 --> 03:52.010 Then you don't have to give the minus sign here. 03:52.760 --> 03:59.240 Now, when I click on Plot, you see that we have a very nice, beautiful plot with the input as blue 03:59.510 --> 04:01.430 and the output as green. 04:02.500 --> 04:06.560 This is the result of a full wave rectifier. 04:07.150 --> 04:15.400 Now we can change this style, so increase the weight so that you can easily understand how the results 04:15.400 --> 04:16.300 actually look like. 04:16.330 --> 04:19.090 Now, there is a potential, a drop. 04:19.090 --> 04:23.890 It is not equal to the voltage, the input voltage, but it's totally fine. 04:24.220 --> 04:25.180 It is realistic. 04:25.430 --> 04:26.290 Oh, definitely. 04:26.290 --> 04:30.000 There will be a potential drop in the other part of the circuit. 04:30.430 --> 04:35.000 So here we have the reason for the full rectifier. 04:35.770 --> 04:41.230 Now you can always change different settings, play around with the value of resistor diode and the 04:41.230 --> 04:43.670 voltage source and check different values. 04:44.080 --> 04:48.700 I will just try in my next lecture, I assure you. 04:48.940 --> 04:50.740 Amazing trick. 04:50.980 --> 04:53.520 You know, to enhance the signal. 04:54.040 --> 05:00.300 I already told you in the theory that fool wave activity is used to convert AC to DC. 05:00.580 --> 05:08.350 So what we will do is we'll try to add a capacitor in the circuit and then try to convert the positive 05:08.350 --> 05:11.080 AC signal here into our DISCIPLE'S. 05:11.710 --> 05:13.180 Let's see how we can do that. 05:13.330 --> 05:17.770 Until then, take care and let's come back in our next lecture.
