This paper presents a realization of the space-vector pulse-width modulation (SVPWM) strategy for control system induction motor (IM). In this paper is presented a space vector PWM algorithm for four switch three phase inverters (B4, FSTPI) based on the one for six switch three phase inverters (B6, SSTPI) (principle of similarity) where the ???? plan is divided into 6 sectors and the formation of...
This paper proposes a new space vector PWM technique for four-switch three-phase inverters (FSTPI) under DC-link voltage ripple condition with the optimization of the amplitude of first harmonic output voltage. The proposed algorithm is based on the establishment of quasi-space-vectors with their maximum length and modulation technique, which is simulated the technique for six-switch three-phase inverters...
This paper aims to achieve the good performances of both the DC boost control and AC output voltage control of the Z-source inverter. The algorithm to control linearly the capacitor voltage is suggested in order to improve the transient response for DC boost control of the Z-source inverter. The peak AC output voltage is used to control exactly the AC output voltage to its desired level. The proposed...
Results of development and research of the charge device with microprocessor control for an operative feed of circuits of DC power complexes are described. The device is executed with an opportunity of modules parallel inclusion of different power. High accuracy of output energy parameters stabilization is achieved: voltage 0,33 % at a level of pulsations no more than 0,24 % in voltage stabilization...
