If the system involves rectification, especially multi-pulse rectification, high-power frequency conversion, or harmonic control requirements, a phase-shifting transformer is needed because ordinary transformers cannot solve harmonic problems at the source.
Filters treat harmonics after they are generated, while phase shifting controls harmonics at the source, so the best solution is usually phase shifting combined with limited filtering rather than relying entirely on filters.
The real differences lie in phase-shifting angle accuracy, multi-winding design quality, and whether the manufacturer truly understands your rectifier system.
An unreasonable phase-shifting design may fail to reduce harmonics, lower rectification efficiency, cause system oscillation, and lead to serious overheating.
We match the phase-shifting angle according to your rectifier scheme, optimize the pulse structure, and help reduce the overall system cost.
By sending an inquiry, you can quickly confirm whether a phase-shifting solution is needed, which rectifier pulse configuration is suitable, and whether there are potential harmonic risks.
