•The converter can start automatically and buffered by kinetic energy；
•The time is related to the specific load and has been verified by the third-party organization.
•The current maximum can be increased to 16 levels;
•The stability of the MV converter has been improved for several times;
•It reduces the unit IGBT failures caused by high-frequency control greatly;
•It makes the stability of the equipment much higher than that of standard equipment.
•Adopt neutral point drift control technology;
•Each phase supports up to 2 levels of bypass;
•It is recommended to use the same level of bypass abroad.
•Fan status monitoring alarm.
•The converter can keep running with damaged fan.
•The converter can accurately locate the fault position of the fan.
•Realize converter expansion;
•Realize hot standby of converters;
•Motors can keep operating with failure of single converter;
