Grid Connection Circuits for Powerful Regenerative Electric Drives of Rolling Mills: Review
AC regenerative electric drives (AC REDs) are widely used in metallurgical rolling due to their reliability, efficiency, and power sufficient to maintain the process. This paper reviews the latest achievements in building the grid connection circuits for the main AC REDs of rolling mills. The paper discusses multipulse connection circuits formed by various transformer types and algorithms for preprogrammed pulse-width modulation with selective harmonic elimination technique (PPWM with SHE) ofdoi:10.3390/en15228608 fatcat:dxhytsq5qfajpm32ckuywfii7q
