Triple line be connected between two concatenated IGBT, the capacitor and protective resistance are connect with IGBT module parallel, and are led to
Overcurrent fuse is connect with DC power supply.
After technical solutions according to the invention, bring it is following the utility model has the advantages that
Two kinds of power supply modes of existing rail traffic vehicles air-conditioning are changed to only direct current supply all the way by the present invention, the present invention
The alternating current that direct current is converted to needs by inverter eliminates the mutual lock control under two kinds of powering modes, sets circuit
It counts simpler, additionally by the frequency for adjusting inverter output, can control the revolving speed of blower, realize that multi gear wind speed is adjusted,
Solve the problems, such as that traditional design wind speed is not easy to adjust, in addition vehicle is during doing type approval test, if air output needs to adjust,
Only need to change the output of inverter it is achieved that not needing change hardware, work obtains biggish simplification.In summary originally
Inventive structure is simple, reduces costs, and saves space, alleviates weight, and speed adjustable range is bigger, comfort is more preferable.
