I a supposed to design a power source device. And this is what has been done in multisim so far, am falling short of time but I really want to know valuable suggestions of the experts over here since I really want to make this design final and robust. Also sine am a beginner in electronics, please can someone direct me on the attachment of oscilloscope and voltmeter to test.
Waiting or your replies.
Thank you
Use a single Ground point and connect all the components to the same ground.
Now for oscilloscope, just connect the A-port across the load.
Same with the voltmeter.
You just have to connect the two terminals of the meter across the load(component) where you need measurements.
Alright, but now I have one more problem. I need a voltage outlet of 220Vac which is capable of supplying fixed or variable DC voltage. I am confused as to how would I make this happen. Thanks alot for your response.
I actually need a 220V ac source since the local main in the country is 220V ac.
And this is what I am getting on the voltmeter. Am not getting why is it showing this value instead of 12V.
The connection of the capacitor C1 is shorting both the output of the transformer. I think there a mistake there.
And if you need a 12V dc at the output you can use a LM7812 IC with the transformer to get a constant 12V dc.
Okay what do you think about this one? I will get a positive voltage supply unless I want a negative one. But the problem is that the voltmeter should show 20Vac and its not. Am really frustrated with this problem. I think there's something wrong with the transformer. What do you think here?
P.S. This is just part of a circuit
