Industrial UPS power consumption is high

The main differences between the industrial UPS and high frequency UPS are embodied in the rectifier and transformer. Industrial UPS rectifier uses SCR device, the voltage stress is small, the current stress is big, the high frequency UPS mainly uses the IGBT device, the current stress is small, the voltage stress is big. SCR and IGBT are currently completed devices, as long as the application properly, there will be no difference in the reliability. In fact, the inverter part of industrial UPS is also use of IGBT, and there is no reduction in the reliability of industrial UPS power supply, and there is no evidence to prove that the inverter is the weak link in the industrial UPS. From the topological aspect, industrial UPS with the phase controlled rectifier + full bridge inverter, high frequency UPS generally with rectifier + half bridge inverter. These topologies are very popular in the electronics technology, and there is no more reliable question, its reliability depends on the level of design.
