Multisim help, h-wave rectifier
« on: November 01, 2013, 02:13:24 am »
Hello all, using Multisim in my school, first time doing it so. Was given an assignment to write and calculate all kinds of things regarding to rectifiers and different types of methods.

Anyway, nothing over the top, but I ask for your help in Multisim. The circuit here was supposed to be with ideal diodes, but it appears to be not. Is there an ideal diode in Multisim somewhere ? Also, what is up with the multimeters, why do they give me such readings ? And lastly, is there a way to project voltage/current vs time on the same screen ?

Thank you for your time

There's no an existing ideal diode model in Multisim. If you want one, you've to create a custom component through the component wizard in the software. As for the voltage readings, you've two equations in the top left corner and they would be enough to tell you why they're like that.

Use transient analysis to project voltage/current vs time on the same screen. See the following link for how to:

Well, if i check the Multisim 11 i use, when placing components there is in group "Diodes" a subgroup DIODES_VIRTUAL containing a virtual diode and virtual zener. I cannot recall if this is a standard subgroup or if it came in some extra package or plugin, but there it definitely is.

A 'virtual diode' model in Multisim /= an ideal diode. You can test it in a circuit and still find a voltage drop.
