In this paper, a novel five-phase five-level inverter based on H-bridge is proposed. Then, the PWM control strategies of this inverter are researched. As the five-phase five-level inverter has 3125 space voltage vectors, it makes SVPWM algorithm extraordinarily complex and too difficult to implement. So, it is a feasible control scheme to adopt carrier-based PWM method. According to phase-shift SPWM...
Aiming at five-phase permanent magnetism synchronous motor (PMSM), this paper sets up the variable-frequency variable-speed system supplied with three-level inverter and makes study about PWM control algorithm of five-phase three-level inverter. In multilevel inverter, switching frequency optimal PWM (SFOPWM) has many advantages such as high voltage usage and simple control, but the calculation of...
Aiming at five-phase permanent magnetism synchronous motor (PMSM), this paper sets up the variable-frequency variable-speed system supplied with three-level inverter and makes study about space vector PWM control algorithm of five-phase three-level inverter. In the control method of voltage space vector, the converter and machine is seen as a whole body, so it has the advantage of good control effect...
