The output voltage of the inverter 'Vout' has five levels in phases b, c, and d (k=2,3,4) and three levels in phase a and e (k=1,5). Therefore, the modulation is working properly. The filtered output voltage 'filtered Vout' of the converter follows the reference voltage 'Vref'. The phase shown in the scope can be selected by means of the 'Phase selection' block. 'Vout(k)' is the switched output voltage of phase 'k'. 'filtered Vout' is the output voltage of 'Vout' phase after been filtered with a low-pass filter. 'Vref' is the sampled voltage reference for each phase. Load neutral is connected to the inverter neutral.

The 'Sequence' block provides the time sequence of switching vectors.ĥ. In Matlab/simulink, the simulation model of the whole system is built, two control loops are used, which are inner current loop and the outer speed loop. Both blocks require the specification of the number of phases and their outputs are a matrix with the switching vector sequence and a vector with the switching times.Ĥ. At the basis of analysis of the mathematical model of the permanent magnet synchronous motor (PMSM) and the principle of field orientated vector control, a novel method for modeling and simulink of PMSM system based on SVPWM is proposed. This block makes use of the block 'Two-level multiphase SVPWM', also described in, that can be used alone with two-level multiphase converters. The 'Multilevel multiphase SVPWM' performs the multilevel multiphase space-vector PWM (SVPWM) algorithm presented in. The 'Normalize' block normalize the reference voltageģ. The 'Sine Wave f' and 'Fifth harmonic' blocks generate an unbalanced five-phase reference voltage with a fifth harmonic.Ģ. The seven-segment SVPWM simulation model is shown in.

The splitting of T0 between vectors O111 and O000 can be manipulated in favor of suppressing the neutral point voltage fluctuation since each vector has the same effect on the pole voltage but opposite effects on the neutral point voltage. This time is implemented by allocating it using the zero vector O111 in the middle of the pulses and O000 on both edges. It is the manipulation of the time assigned for the zero-vector. In this contribution, another suppression method is combined with the previous one. In the previous contribution, the suppression technique is limited to the swapping of redundant vectors. The author of this contribution has previously contributed an algorithm that doesn't exploit the possibilities for suppressing the neutral point fluctuation. The SVPWM technique is the most suitable one for encoding onto DSP and microcontrollers since these devices have suitable dedicated H/W resources that can receive slow rate updates of the duty cycle (for example at 50 to 100 microseconds) and produce very fine PWM resolutions using their integrated capture compare H/W modules.
