Hi. I'm a electrical and electronics engineer with experiences in the design of power electronics devices, 1 of them is the Variable Frequency drive (VFD). If you look on my profile you can see an scientific article where I use the Space Vector Modulation (SVM) algorithm, implementing this in a electronic circuit with a arduino that provides the SVM signal and with the electronic circuit (Inverter) this signal is amplified to a AC three phase induction motor. Please choose me for this project and you will not regret. Thanks and regards
