I've tried several different topologies, such as the full bridge rectifier and the following which I've successfully tested on other simulators.

Circuit

However, on Cadence I always end up getting static like this in the output...

Graph

Just be honest. Is it me? Or is it Cadence.

Edit:

Here is a picture of the circuit in Cadence.

Here is a picture of the output run from 0s to 3750us.

Here is a picture of the output run for 3s total.

It's hard to tell what the problem is as you don't show the simulation specific parameters which cadence/pspice needs for it to function. But it seems to work fine for me:

  • \$\begingroup\$ I like big loads. But why is that 10M there? I've legit stayed up all night tryna get this sucker to work. Also, what library is the transformer he used in? \$\endgroup\$

    \$\begingroup\$ @snowg: Both sides of the transformers needs to be referenced to a ground node for the simulator to be able to work. Therefore you add a big resistor to to ground, so the simulator can do it calculations. Its a simulator quirk. The transformer is formed from two inductors, "L", and with the k_linear parameter to specifiy that they are coupled together. \$\endgroup\$

It looks to me like you need to use the "earth" symbol somewhere so that 0 volts is defined. At the moment there doesn't appear to be an earth on your circuit but that might be because you've cut-off the picture. Hopefully it's as simple as adding an earth node (as what is required in most simulators).

Try adding it at the junction of the two smoothing caps (1 uF). You might also want to explain why the diodes are "N4007" types instead of "1N4007".
