| Abstract: | The performance and peculiarity of a series of DSP-TMS320LF2407,and the peculiar application of DSP on frequency-variable speed adjustable system were introduced, the principle and method of voltage space vector producing symmetrical PWM waveforms were discussed. It concludes that using voltage space vector will reduce output current harmonics in converter and harmonics losses of motor,effectively utilize power voltage,and consumedly enlarge speed-adjustable scope of motor. This system block diagram of part of program,PWM initialization program and experimental results were presented. |
