# Diode Bridge in Simulator not behaving as expected

Hi I have a Diode Bridge as outlined in the image below. As you can see I am getting a negative voltage on one pair of diodes instead of this voltage being flipped to positive.

Can you see anything wrong with my design or does it look like the simulator program getting it wrong?

• Yep, that's LTSpice - I'm sure Micheal is aware of this, but since it seems relevant, a tip for differential measurements for anyone else who is relatively new to it, is to click and hold the left mouse button on one node, drag it to the other node (the probe will should turn black) and release. You will now get a trace that is the difference between the two nodes (instead of e.g. one node and circuit ground) It will be labelled something like V(N001, N002) – Oli Glaser Jan 14 '13 at 15:10
