Abstract:
A series-parallel rectifier system and methodology, employing multiple parallel rectification paths is disclosed. The system includes a dual winding AC power supply and a rectifier apparatus coupled to the AC power supply. The rectifier apparatus is comprised of rectifier legs interconnected in a parallel circuit relationship, where each leg comprises several rectifiers including a connection in series and oriented to conduct current from a negative DC bus to a positive DC bus. Bypass legs comprising two rectifiers including a connection in series and oriented so as to conduct current from said negative DC bus to said positive DC bus are added in place of redundant rectifier legs and interconnected with the AC power supply.
