Trixbox is a software tool that allows users to do their end to end control system design for digital power conversion for power electronics applications. Control system can be trivial and extremely complex at the same time. It can be trivial when trial and error methods are used. It can be extremely complex when proper analysis and systematic approach is required. Trial and error is quick and dirty but may not always meet the specs and handle various corner cases. A systematic approach is complex and mathematically involved and requires considerable skill and expertise. Trixbox uses systematic analytical methods to get your design started quickly.
