In terms of reliability, the power frequency machine is better than the high-frequency machine. The power frequency machine adopts SCR rectifier. After more than half a century of development and innovation, the technology has been very mature, and its current impact resistance is very strong. Because SCR is a semi control device, there will be no through, false trigger and other faults. In contrast, although the switching frequency of IGBT high-frequency rectifier used in high-frequency machine is higher, IGBT has strict voltage and current working area and low anti impact ability. Therefore, in terms of overall reliability, IGBT rectifier is lower than SCR rectifier.
