| Abstract: | A new kind of testing equipment for electric passenger train inveter is proposed.Its data acquisition subsystem is based on TI's high perfomance-price ratio digital signal processor TMS320C32,which could collect inveter's signals in high speed.At the same time,through a fast Fourier transform with Blackman window function,could analyse the output quality of the inverter.The PC displays the signal from the DSP,and reports the state of the inverter via an expert diagnosis system. |
