Comprehensive Review on Main Topologies of Impedance Source Inverter Used in Electric Vehicle Applications

Abstract

Power electronics play a fundamental role for electric transportation, renewable energy conversion and many other industrial applications. They have the ability to help achieve high efficiency and performance in power systems. However, traditional inverters such as voltage source and current source inverters present some limitations. Consequently, many research efforts have been focused on developing new power electronics converters suitable for many applications. Compared with the conventional two-stage inverter, Z-source inverter (ZSI) is a single-stage converter with lower design cost and high efficiency. It is a power electronics circuit of which the function is to convert DC input voltage to a symmetrical AC output voltage of desired magnitude and frequency. Recently, ZSIs have been widely used as a replacement for conventional two-stage inverters in the distributed generation systems. Several modifications have been carried out on ZSI to improve its performance and efficiency. This paper reviews the-state-of-art impedance source inverter main topologies and points out their applications for multisource electric vehicles. A concise review of main existing topologies is presented. The basic structural differences, advantages and limitations of each topology are illustrated. From this state-of-the-art review of impedance source inverters, the embedded quasi-Z-source inverter presents one of the promising architectures which can be used in multisource electric vehicles, with better performance and reliability. The utilization of this new topology will open the door to several development axes, with great impact on electric vehicles (EVs).

A Review of DC-AC Converters for Electric Vehicle Applications

“…VSIs and CSIs have some restrictions; thus, they are not appropriate for some types of applications. For example, VSIs cannot boost the voltage level, and CSIs cannot decrease the voltage level [24]; therefore, they cannot work independently for a variety of applications. Furthermore, sudden variations in the switch voltages and currents cause severe switching losses and EMI problems on the switching devices and for the motor supplied from the VSI or CSI [25,26].…”

Interface Converters for Residential Battery Energy Storage Systems: Practices, Difficulties and Prospects

“…There is a variety of impedance source networks proposed in the literature for a range of applications with different properties and features (Figure 16), including three-phase and multilevel configurations [117]. The majority of basic impedance source topologies were initially unidirectional; however, some studies address the bidirectional versions potentially suitable for residential BES [118,119].…”

Application of a Control Scheme Based on Predictive and Linear Strategy for Improved Transient State and Steady-State Performance in a Single-Phase Quasi-Z-Source Inverter

“…Power inverters are currently used in a wide range of industrial applications, and will be essential for the operation of future distribution networks [ 1 , 2 ]. Depending on users’ needs, different types of inverters can be used to feed different types of load, such as voltage source inverters (VSI), current source inverters (CSI), and impedance source inverters (ZSI, qZSI, and similar) [ 3 , 4 , 5 ].…”
