GTO-PWM-UPS Inverter

摘要

The UPS inverter presented in this paper uses GTO as power switch components and a HEF4752 as the PWM controller of the inverter, together with a single-chip microcomputer being the error diagnosis system for the UPS inverter.rnIt is an important research field to increase the energy utility rate owing to a world-wide energy crisis. UPS systems have been greatly improved mainly focusing on how to increase transforming efficiency, to lower power loss ( more than a half of the loss is due to main power electronic components switching on and off ), to simplify circuit and decrease material consumption loss. There are still a lot problems to be studied and tested.
