| The circuit of the general inverter based on the TMS320F240 DSP was designed in this paper, and the practicable program was compiled. A prototype was made and tested,and the result indicated the circuit is credible and the program run well. In this paper, a software method identifying the phase lack was proposed. Tests indicated it is simple,useful and effective.The effect of the dead time to the inverter system was lucubrated,and mechanism of the dead compensation was analysed. Through the comparison of several different schemes, an availability method was found to compensate the dead time in general inverter,and the results of experiments indicate the method is feasible and valid. |
