Library's collection Library's IT development CancelOne of the inverter methods is Pulse Width Modulation methods. The
sinus digital signal wich is genereted by Pulse Width Modulation signal is
produced by minimum system 8031. The minimum system 8031 has also settled
the entire work process: circuit included, LCD control, keypad and devider in
order to dispose frequency and voltage.
Based of experiment results, the utilisation of Pulse Width Modulation
methods to inverter, this fact can be indentivied from the aplicatoin of smaller
current for smaller RPM, so mat linear graphic can be drawn for the relation of
RPM and current The toque produced fits the comparison of the current
declination to frequency. The experimental error is 1,0412%.
