Abstract—The 12-pulse rectifier is often used to supply highpower
industrial loads. Its ability to effectively and cheaply mitigate
the harmonics on the ac side has ensured its dominance in
the industry even as active front ends become cheaper and more
reliable. Despite its many benefits, the 12-pulse rectifier is not able
to reduce the ac-side harmonics to a level acceptable by the pertinent
IEEE standards without additional filtering.
