Multilevel drive supply can be realised in two different ways, by using either a conventional multilevel single-sided supply configuration or with a dual-inverter supply topology. The second structure is simpler for practical realisation, since the problem of capacitor voltage balancing does not arise. This paper develops a space vector PWM (SVPWM) algorithm for the dual-inverter six-phase supply,...
This paper presents a comparative study on fuzzy rule-base of fuzzy logic speed control with vector-controlled permanent magnet synchronous motor (PMSM) drive. Fuzzy rule-base design is viewed as control strategy. All fuzzy rules contribute to some degree in obtaining the desired performance. However, some rules fired weakly do not contribute significantly to the final result and can be eliminated...
Most of the researches for adjustable speed drive focused on voltage amplitude control. However, its only control speed in the constraint limits. Adjustable frequency drives have not been widely used with single-phase induction motors. The scalar control law used for many three-phase inductions motor cannot be used in all operating regimes of the single-phase motor. Calculations show that the slip...
