Bridge Rectifier
January 4, 2020 - 3:45am


I am a novice with electronic circuits, but attempting to expand my knowledge.  I am trying to convert 14VAC to 12VDC with about a 15A load on a riding lawn mower for LED lights.  I installed a 200V 60A Bridge Rectifer (NTE53016) and my output voltage is only 4VDC at full rpm on the stator.  I also installed a 4700uf capacitor across DC + and -.  Am I correct in assuming my bridge rectifer is too large for my project?  Would a GBU1510 be a better choice to achieve my 12VDC output?  Kind Regards!

Hi Paul, which Transformer rating you are using to get 14 VAC? It will be better if you can share the complete application circuit connections.

The input AC spec is required for answering your question.

Also, the bridge rectifier need to have a heat sink. What kind of heat sink you are using for the bridge rectifier?
