A novel modified space vector pulse width modulation (MSVPWM) strategy for Z-Source inverter is presented. By rearranging the position of shoot-through states, the frequency of inductor current ripple is kept constant. Compared with existing MSVPWM strategies, the proposed approach can reduce the maximum inductor current ripple. So the volume of Z-source network inductor can be designed smaller...

In this paper, an attempt has been made to investigate analytically the dynamic performance of selfcommutating current source inverter-fed induction motor drive with volts/Hz control strategy. Speed and current PI regulators are used in realization of closed loop control structure of the drive system. The closed loop mathematical modeling of the complete drive system is presented in the synchro...

The voltage source inverter (VSI) and current voltage source inverter (CSI) are widely used in industrial application. But the traditional VSIs and CSIs have one common problem: can’t boost or buck the voltage come from battery, which make them impossible to be used alone in Hybrid Electric Vehicle (HEV/EV) motor drive application, other issue is the traditional inverter need to add the dead-ba...

Abstract: The generator stator current gets distorted with unacceptable levels of total harmonic distortion (THD) because impedance-source wind power generation systems use three-phase diode rectifiers. The stator current harmonics will cause increasing losses and torque ripple, which reduce the efficiency and stability of the system. This paper proposes a novel half quasi-Z-source inverter (H-...

This paper presents a high-efficient, low cost inverter system suitable for solid oxide fuel cell applications. The proposed inverter provides a solution for the lowvoltage/high-current fuel cell source by using power modules that are parallel connected in the input and series connected in the output of DC-DC boost modules. The inverter topology is analyzed and outlined. A prototype is develope...

Multilevel inverters have been developed due to limitations of the conventional two-level voltage source inverters (VSIs). Most of the topologies of multilevel inverters that have been presented in the literature are based on the sharing of the rated voltage between the switches so that the switches with lower voltage ratings can be used. In these topologies, the current rating of all of the sw...
