Received Apr 6, 2016 Revised Nov 11, 2016 Accepted Nov 23, 2016 The adjustable speed drives employ PWM converter-inverter system in order to obtain unity power factor. The DC inrush current in DC link capacitors of the rectifier limits the operation of power devices. Hence, this paper proposes a new approach to reduce the DC inrush current by employing modified Z-source inverter in a Adjustable...

Abstract— In this research, a single phase Z-source cascading Multilevel Inverter, Nine-level inverter topologies with a trinary DC sources are offered. The recommended topologies are expanded by cascading a full bridge inverter with dissimilar DC sources. This paper recommends advanced pulse with modulation technique as a switching scheme. In this PWM technology, trapezoidal modulation techniq...

Three-level Z-source inverters are recent single-stage topological solutions proposed for buck-boost energy conversion with all favorable advantages of three-level switching retained. Despite their effectiveness in achieving voltage buck-boost conversion, existing three-level Z-source inverters use two impedance networks and two isolated dc sources, which can significantly increase the overall ...

In the conventional DC-AC inverter consisting of two DC-DC converters with unipolar output capacitors, the output capacitor voltages of the DC-DC converters must be higher than the DC input voltage. To overcome this weakness, this paper proposes a single-phase DC-AC inverter consisting of two embedded Z-source converters with bipolar output capacitors. The proposed inverter is composed of two e...
