| Abstract: | The main circuit structure and working principle of variable voltage variable frequency(VVVF) inverter were introduced.The power used 80C196 microcomputer as the core.The new techniques and modularized structures were adopted,such as digital frequency division,D/A conversion,instantaneous value feedback,sine pulse width modulation,IGBT output,etc.There were many properties such as high load adoption,fine characters of output waveform,simple operation,small cubage,light weight,as well as the protection function of over current,overload,overheat,short circuit,which ensured it to work reliably. |
