Abstract: Introduction was made to a kind of quick double power supply diverter switch based on insulated grid bipolar transistor (IGBT).Description was made to its working principle, structure of switch unit body and switching process. Matlab software was used to build the simulation model. The 220 V low-voltage sample machine was developed, the experiment carried out. Simulative and experimental results show that the diverter switch is with swiftness and transient stability, within 4ms for actual switching time, being able to meet harsh requirement of sensitivity and key load for power supply reliability and continuity.
Key words: power quality; quick diverter switch; insulated grid bipolar transistor; double power supply; switching process
