Double-conversion UPS path
A double-conversion UPS continuously conditions the protected path, but its bypass, loading and loss behavior remain part of the design.
How it works
Convert incoming AC through a DC link and inverter while stored energy supports the inverter when the normal source is unavailable.
Where it fits
Protected loads needing defined ride-through and power conditioning within a maintainable critical-power architecture.
Where it breaks
The topology is selected from a headline efficiency or runtime figure without load curves, bypass states and downstream dependencies.
Tradeoff register
- Continuous conditioned path
- Conversion losses vary with loading
- Static and maintenance bypass states need explicit review
