“…There are attractive advantages in electric vehicle and renewable energy applications especially due to the constant current from the source. In [22] the characteristics of the 3LqZSI are compared to the 3LZSI. If separated DC power supplies are available, a quasi-Z-source cascade multilevel inverter-based system is a mentionable topology for high voltage applications or for use in photovoltaic (PV) applications regarding the modular structure, the ability to always capture maximum PV power and the reduced number of required components compared to the 3LZSI [23][24][25][26][27].…”

Z-source inverter (ZSI) combines the electrical function of a DC/DC converter and a three-phase inverter. This study deals with a three-level neutral-point-clamped (NPC) ZSI which brings an additional electrical potential. The benefit is the lower output current ripple of each phase. Due to the non-linear behaviour of the Z-source control path, designing an accurate and especially a dynamic control can be challenging. This study presents a design of an adaptive control for a three-level NPC ZSI to fulfil the previously mentioned goals. The correct functionality of the control system is underlined with measurements at different operating points. A possible application field for threelevel ZSIs are hybrid and electric vehicles.

Voltage source and current source converters are used in industrial applications as either boost or buck converters for a defined power flow direction. These operational modes limit these converters to be utilized on their own in hybrid and electric vehicle (EV) applications. Z-source (impedance source) converters, on the other hand, have the capability to be operated as buck and boost converters to have a wide range of output levels. The boost ratio of the direct current link voltage of a Z-source converter is set by short-circuiting the phase legs of the converter and defining the overlap duration at each switching period. In order to have the optimum efficiency with the lowest possible total harmonic distortion, a modified space vector pulse width modulation method with an impedance network could be selected for closed-loop control of the quasi-resonant Z-source converter to drive permanent magnet synchronous motors (PMSMs). In this study, closed-loop vector-controlled drive systems built with two-level and three-level boosted voltage source converter topologies and two- and three-level quasi Z-source converters for field-oriented control of a PMSM in EV motor drive applications were compared under constant motor speed–constant load, constant speed–variable load and variable speed–constant load operating conditions.
