Short Content:     The high usability power source's digital management has the future greatly, but this kind of digital management is frequently take uses the high cost the complex multi-chip electric circuit solution as the price. For example, has the voltage/electric current surveillance and the power source allowance control application possible need many integrated circuit, like the low drifting datum, the resolution are at least 12 multichannel differential input ADC, 8 DAC and the special-purpose micro controller. In addition, realizes the allowance ...

Short Content: Abstract: Proposed produces the SVPWM wave with DSP to realize the entire numerical control one method to the contravariant power source. In has analyzed in the TMS320LF2407A digital signal processor chip characteristic foundation, has given the system design software and hardware structure. The experiment indicated that the system circuit is simple, the reliability is high, but the promotion is strong.Key word: Invertor; Digital signal processor; Digitization; Space vector pulse-duration modulationO introduction    Along with information technology's development, the 400Hz intermediate frequency ...
