What it represents
A three-phase bridge rectifier converts a documented three-phase AC input into a DC output. Its input phase terminals and DC polarity must be identifiable.
How to read it
- Check the rectifier's output and any smoothing network as separate circuit elements.
- The preview is an original explanation of this function. Match the actual drawing convention to its legend and the selected equipment documentation.
Information to show or reference
- Label three AC phases
- Mark DC polarity
- Reference rectifier ratings
A distinction that matters
Three-phase rectification differs from a single-phase bridge connection.
