Performance comparison of frequency machine and high frequency machine

(1) In terms of reliability, the power frequency machine is better than the high frequency machine

The power frequency machine adopts a thyristor (SCR) rectifier. After more than half a century of development and innovation, the technology has become very mature and its anti-current impact capability is very strong. Since SCR is a half controller

There will be no straight-through, false triggering and other faults. In contrast, although the IGBT high-frequency rectifier used in the high-frequency machine has a higher switching frequency, the IGBT has strict voltage and current operation during operation.

Regional impact resistance is low. Therefore, in terms of overall reliability, IGBT rectifiers are lower than SCR rectifiers.

In addition, when the mains and the generator are switched, the high-frequency generator often has to be switched to the bypass due to the lack of the neutral line, which may cause a major failure of the load flashing under certain working conditions. Because the rectifier does not need the neutral line to participate in the work of the power frequency machine, when the neutral line is disconnected, the UPS can maintain normal power supply.
