| Profile | The invention provides a numerical control method for inverter and DC frequency converting. The method makes pre-processing base on defined modulation waveform to calculate control numerical sequence and its lasting time, and eventually forms on-off modulation waveform. Steps include: Firstly, logic switch “0” or “1” are used to represent the shutdown or on status of power switch triodes, and the numerical codes for power switch triodes of entire IC are formed by ranging “0” and “1” in certain sequences. Then, the lasting time of each status is calculated based on modulation waveform and period determined by frequency for output alternating voltage. Lastly, numerical code sequence and lasting time of corresponding status of entire IC power are output in line with data obtained in pre-processing stage, and the modulation waveform of switch is formed. The aforesaid numerical codes should be represented by hexadecimal numbering system. The method can realize the pre-processing of massive computing work and reduce the costs of frequency conversion technologies.Applications:Now, the invention has been applied in aviation, aerospace, solar energy inverter, wind power inverter and UPS/EPS sectors. Financing is hoped to promote its industrialization as soon as possible.Cooperation method:10 million yuan to 20 million yuan |
