The voltage-source inverters are normally equipped with an electrolytic capacitor in their DC link. The electrolytic capacitor has several disadvantage such as increasing size, limitting converter life and reliability. Therefore, several approaches for removing the DC link capacitor have been studied. This paper proposes a new strategy of the voltage source inverter without DC link components. To restrain the current resonance caused by <i>LC</i> filter of AC source side, rectifier of this inverter is controlled by current closed loop with <i>di</i>/<i>dt</i> feedback (<i>di</i>/<i>dt</i>; differenciation of AC source current). To improve AC source current waveform, feedback gain of <i>di</i>/<i>dt</i> and <i>LC</i> parameters are investigated by calculation for a 0.75kW induction motor driven by this inverter. Both the calculated and measured waveforms of AC source currents maintain nearly sinusoidal waveforms with a unity power factor.
