In the first part, the authors present a topology of nine–level NPC VSI, then we propose a model of this converter and an optimal PWM strategy to control it using eight bipolar carriers. Then in the second part, we study a new high voltage cascade nine-level PWM current rectifier–filter–nine–level NPC VSI–PMSM.

The quality of a VSI output voltage is often benchmarked by the total harmonic distortion (THD) that it produces. If V f is the fundamental voltage, the THD for line to line voltage is given as: (12) THD = ∑ i = 1 ∞ V 6 i ± 1 2 V f. In Eq. , the THD defines the non eliminated harmonics components present in …

The cascade feed system The Barmac S-Series VSI uses the cascade feed system to introduce a second stream of material, in a controlled quantity, into the crushing chamber turbulence. This causes a supercharging of the particle population within the chamber, thereby improving the energy transfer between the particles.

Thus, they study a cascade constituted by two-level PWM rectifier-filter-seven level NPC VSI. This study shows the effect of the stability problem of the DC voltages on the PMSM performances.

Thus, they study a cascade made up of two two‐level PWM rectifier—seven‐level NPC VSI. The results obtained show that the input DC voltages of the inverter are not stable but are better than the ones obtained with a cascade which uses one PWM rectifier.

Speed control in the case of a VS-cascade control with VSI in the internal loop. Case A: set point; case B: speed output The prefiltering law is now less mandatory for the t)re-reduction of the set-point (the physics of the 364 plant is now respected through the combined action of the two VS-controllers), but it is remarkable that the ...
