Regeneration of power is not possible in power electronic converter system?
Homework Answers
No it’s possible.
suppose if you consider single phase fully controlled converter with inductive load. If we operate the firing angle greater than 90 degrees then it operates as inverting mode of operation. Now load delivers power to the source then regeneration takes place.
