The rectifier may comprise a first interleaved phase-leg, a second interleaved phase-leg, and/or a third interleaved phase-leg. Respective interleaved phase-legs may comprise positive portions configured to conduct positive current from a transformer towards a load, and negative portions configured to conduct negative current from the load back to the transformer. The rectifier may be configured to sequentially cycle respective interleaved phase-legs into positive and/or negative 120 conducting states over a 360 degree cycle to output the 12-pulse DC voltage. For example, during a first 120 degree conducting state a positive portion of the first interleaved phase-leg may conduct positive current towards the load, while a negative portion of a different phase-leg may conduct negative current back to the transformer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rectifier for converting three-phase AC voltage to 12-pulse DC voltage","description":"A rectifier is configured to convert a three-phase AC voltage to a 12-pulse DC voltage, drawing a 12-pulse AC current from a three-phase network.
