Now to simulate, you can click F5 or go to the tab Simulate -> Run.Īfter that, you double click the multimeter icon, and it will appear in a small window. You will find it under Simulate tab -> Instruments -> Multimeter.ĭrag the multimeter and connect its pinouts into the J2 connector. In order to verify the voltage in J2 (the battery connector), we will need to place a voltage meter in it. There you can set 19v (as the battery needs at least 12.7v to charge). We can change it by right-clicking it and going to Properties. You will find it under the Source group-> Power_source.Ĭonnect the power and the ground as it shows in the figure below: Go to Select a component window and add VCC and Ground. You now should have something similar to the following: Once you click on the first pin, you see that the mouse icon changes, and a trace appears following the mouse. To make the connection, you just need to click on the pins of the two components you want to connect. You should have something like the figure below: To rotate it, you can use the ctrl+r shortcut. Now that you have all the components, you can change their position by selecting the Component and dragging the Component. The power connector is PJ-007, and the terminal block is 282834-2. We will also need to connect the power connector and a two-pin terminal block for the battery. Now, repeat the process with all the other components from the schematic. The window will close, and the Component will be placed wherever you left-click in the schematic area. To place the Component, select the one that you want and click Ok. You should pay attention to the footprint, as you are going to use it in your layout. There will be different versions of the same Component. The figure below shows the essential information about this window. You can type the Component that you want or go to the Group dropdown menu. The “Select a Component” window will open. For that, you can either go to Edit tab -> Component or press ctrl+w. Once you open Multisim, the first thing is to add the components. This circuit is usually used for a Lead-acid 12V battery. In the figure below, we have a current controlled battery charger circuit using LM317.
