| Abstract: | Taking the coal mine main shaft elevator high efficiency three levels variable-frequency adjustable-speed system in mine as an example,this article has given three level invertors main circuit and invertor’s structure topology.It carries on the analysis to driving circuit’s logical organization and connects the use existence to IGCT in the convector circuit,the question to carry on the analysis.Emphatically,the static state presents the reason which the voltage is imbalanced produces to carry on the thorough discussion,gives the solution. |
