Abstract :
The voltage-source inverters are normally equipped with an electrolytic capacitor in their DC link, the electrolytic capacitor has several disadvantages such as increasing size, limiting converter life and reliability. Therefore several approaches for removing the DC link capacitor have been studied. This paper proposes a new voltage source inverter without DC link components, whose rectifiers are controlled by suitable current feedback to adjust near-sinusoidal AC source current waveforms at unity power factor. The calculated characteristics are described for a 0.75 kW induction motor driven by this inverter
