IGBT vs. SCR Rectifier
Why use an IGBT rectifier instead of a SCR rectifier? Compared with SCR rectifiers, IGBT rectifiers can run continuously for 24 hours. IGBT rectifier consumes at least 15% less power than SCR rectifier The IGBT rectifier is less affected by power fluctuations, 100% output, no additional capacity is required. The IGBT rectifier adopts AC-DC-AC-DC topology, 3-phase AC is first converted to DC, in which there are capacitors for energy charging and discharging, which will suppress power fluctuations. The SCR rectifier does not have the function of energy buffering, it is directly affected by the power fluctuation of the grid. The time required for IGBT rectifier plating is shortened by 40%. Low grid pollution, power factor>0.93 Lower cost Feature IGBT Rectifier SCR Rectifier Reliability High High Power Consumption At least 15% lower - Impact of Power Fluctuations Smaller Larger 100% Output, No Extra Capacity Yes No Plating Time Reduction Shorter (40% reduction) - Size and Weight Small
