Locomotive Air Conditioning Control System

In this paper the design and realization of power control system used for air-condition in electric locomotive is performed. It includes two parts which is software section and hardware one. At the same time Svm arithmetic is studied and the distortion of current wave form in voltage type PWM system analysed. At last it expatiates control software used for the system how to design and realize, which focuses on introducing how to realize Svm arithmetic in MCU(cmp88eh47) platform from Toshiba. This system fully reaches the desire of design and get the technique authentication report which comes from Electric Product Intendance And Checking Institution Of ShaanXi.
