Question:Specification of 12 pulse input transformer for GPD505/506- PC5/P5 series AC drive.
Answer:Introduction:

The GPD505/506-PC5/P5 models of 18.5kW and higher can be equipped with 12-pulse input power supply to minimise of harmonic input distortion. To utilize 12-pulse input, a transformer with a dual star-delta secondary is required. The Specs. of the needed transformers are listed below.

The 12-pulse option can improve current distortion by 76% compared to an inverter that uses a 6-pulse input rectifier.
