Why Is My Full Bridge Rectifier Output Still Positive?

Click For Summary
SUMMARY

The discussion centers on the challenges of creating a negative full bridge rectifier circuit. The user attempted to reverse the diodes in their full bridge rectifier setup but found that the output waveform remained positive. It was clarified that merely reversing the diodes does not alter the circuit's functionality, as the configurations are essentially equivalent despite their visual representation. The key takeaway is that proper circuit design and understanding of diode orientation are crucial for achieving the desired negative output.

PREREQUISITES
  • Understanding of full bridge rectifier circuits

I wanted to make a negativer full bridge rectifier circuit and filter it, so that after it went past the bridge, the output voltage would be full wave but negative. Tried reversing the diodes on the actual full bridge rectifier but doesn't work.

Refer to the diagram on the left,is it correct? My output waveform is still positive.

You haven't really reversed anything at all between the two circuits. They are simply drawn differently.
