This DC-link voltage is regulated using a PI controller, whose output is the shoot-through duty ratio Dsh. The DSVPWM pulses with the shoot-through duty ratio Dsh is realized using DSVPWM technique by programming the TI microcontroller. The flow chart for DSVPWM technique is shown in Figure...
A stator flux oriental vector control technique, taking saturation and cross coupling into account, in a flux switching permanent magnet machine was presented, to minimize volume and cost, and reduce cogging torque, noise and vibrations. The d-q axis inductances have been identified using an ...
Vcs*= Vmcos(θ − 240°) = Vabcs_min* The offset voltage of the ABC winding group inFigure 4region 1 to apply SVPWM is equal to Equation (5). Vabc_offset= −(Vabcs_max*+ Vabcs_min*)/2 = −(Vas*+ Vcs*)/2 (5) ...
