12-pulse rectifier is extensively used in high power rectification. and the delta-connected autotransformer and wye-connected autotransformer are its two most popular phase-shift transformers. This paper compares the 12-pulse rectifiers using the two transformers via calculating the input line current. load voltage. https://www.getpureroutine.com/mega-deal-natio-celebrate-eyeshadow-palette-online-amazing-offer/
