  • Model Predictive Control of Impedance Source Inverter

    The control strategy of the power converter plays a crucial role in ensuring reliable and efficient operation of renewable based distributed generation (DG) systems. In most applications, proportional-integral (PI) based cascaded control structures have been used to control current, voltage, etc. To eliminate the drawbacks of the cascaded control structure and difficulties of the modulation techniques, this chapter examines the model predictive control (MPC) technique for impedance source - Z-source (ZS) and quasi-Z-source (qZS) - three-leg, four-leg, and multiphase inverters. Then, it presents ZS/qZS three-phase three-leg, four-leg, and multiphase (five-phase) inverter topologies, along with a description of the topology, model, and switching schemes for control. After that, the MPC algorithm for ZS/qZS three-phase, three-leg, four-leg, and multiphase (five-phase) inverters are presented. Finally, to prove the addressed MPC strategy, a performance investigation has been carried out with qZS four-leg inverter and simulation results are presented to demonstrate the capabilities of the MPC.

  • Design of Z-Source and Quasi-Z-Source Inverters

    Inductance and capacitance are the two main parameters to be designed in the Z-source/quasi-Z-source inverter. This chapter focuses on the network parameters, loss calculations, voltage and current stress, coupled inductor of Z-source/quasi-Z source inverters and also efficiency, cost, and volume, in comparison to the conventional inverter. For three-phase qZSI, the inductor and capacitor should be designed to limit the switching frequency current and voltage ripple. However, for single-phase qZSI, the double line-frequency ripple will be the main concern for design of the inductor and capacitor, because larger inductance and capacitance are required to limit the switching frequency ripple. The total loss consists of those of the H-bridge device, qZS diode, inductor, and capacitor of qZS network. The voltage and current stresses depend on the modulation methods. The presented modeling, circuit analysis, and power loss evaluation provided an illustration for the future building and development of impedance source inverters/converters.

  • Current-Fed Z-Source Inverter

    This chapter presents recent topology modifications to the current-fed Z-source inverter/quasi-Z-source inverter (CF-ZSI/qZSI), its operation principles, modulation, modeling and control, passive components design guidelines, and applications. There are two types of three-phase inverters: voltage source inverter (VSI) and a current source inverter (CSI). The open- circuit state of the CF-ZSI can be used to boost the output current (voltage- buck operation) without the unwanted interruption of source current. There are many topology modifications either to overcome the drawbacks of the basic voltage-fed Z-source inverter (VF-ZSI) topology or to increase its voltage gain. Most of these topology modifications can be adjusted for the CF-ZSI. The CF-ZSI/CF-qZSI has an additional zero vector: an open-circuit switching state, which is forbidden in traditional CSI. The current stress and voltage stress of the Z-source network passive components and input inductor also need to be analyzed in order to properly design the capacitor and inductor in the circuit.

  • Z-Source Inverter for Motor Drives Application

    This chapter presents an overview for the Z-source inverter (ZSI) as an emerging topology for power electronics dc/ac converters in general purpose motor drive applications. Different ZSI topologies, different motor types with different phases, and different control algorithms will be reviewed as a part of the ZSI motor drive system. In addition, various applications of the ZSI in the automotive field will be highlighted. Due to its compact and simple structure, reliable operation, higher power density, higher efficiency, low maintenance costs, simple control algorithms, the permanent magnet brushless dc motor (PMBDCM) has been widely used in industry. The chapter presents different examples of utilizing the Z-source inverter for various vehicular applications. In summary, the Z-source inverter adjustable-speed drives (ASD) system has several unique advantages that are very desirable for many ASD applications, such as ride-through capability during voltage sags, reduced line harmonics, improved power factor and reliability, and extending the output voltage range.

  • Energy Stored Z-Source/Quasi-Z-Source Inverters

    This chapter addresses the quasi-Z-source inverters (qZSI) with battery paralleling to C2for a PV system as an example. The dynamic model and the control method, including battery energy management, PV power maximum power point tracking (MPPT), and grid-tie synchronization, are presented. Similar methods can be performed with the Z-source inverters (ZSI) or when battery connecting to C1. Example simulations are demonstrated in different cases of battery state of charge. The energy storage battery integrated ZSI/qZSI deals with power management among the renewable energy sources, grid, and battery in single-stage power conversion, without the extra dc-dc battery charging converter, providing simple topology and control. Its small-signal model was built to design the controller, especially battery current and energy management control. Simulation results were illustrated for different cases of battery state of charge. The solution is also inheritable to the other derived impedance topologies with battery paralleling to the capacitors.

  • Impedance Source Multi-Leg Inverters

    Standalone distribution generation (DG) systems have recently received much attention for their advantages in supplying power to remote customers. To eliminate the drawbacks of the two-stage dc-dc converters and three-phase voltage source inverters (VSIs), this chapter examines the Z-source four-leg inverter, starting with an analysis of the unbalanced load, and the effects of an unbalanced load. Then, it introduces the different inverter topologies for mitigation of unbalanced conditions. The chapter presents impedance source multi-leg inverters, which consist of three-phase four-leg inverters and five- phase inverters. It investigates ZS/qZS three-phase four-leg inverters with a detailed mathematical model, switching schemes including SVPWM and carrier- based PWM. Then, to analyze buck and boost conversion modes of qZS four-leg inverter, experimental results were presented in different case studies. The chapter presents the qZS five-phase inverter with mathematical model and switching schemes including various SVPWM techniques.

  • Z-Source DC-DC Converters

    When realized as a dc-dc converter, the introduced Z-source impedance network must similarly be short-circuited for a certain defined duty ratio per switching period. The basic operating principles therefore remain unchanged, except that the rear-end converter bridge is changed to one suitable for performing dc-dc conversion. This chapter introduces a few possible dc-dc Z-source topologies for illustration, but will not move deeper into their mathematics since they are almost the same as for dc-ac inversion. This advantage has also been utilized to design multiple converters operating in parallel to achieve a higher power level and premium power quality along with improved system efficiency. The concept of the shoot-through duty cycle to control the output voltage is ruled out completely by simple control of the duty cycle of the switches. Each of the dc-dc converters mentioned above therefore has its unique advantages and disadvantages, which can make them suitable for certain applications but not others.

  • Future Trends

    The parameter optimization for single-phase quasi-Z-source inverters (qZSI) is still an open topic owing to its superior advantages and widespread applications. This chapter presents the future trends of impedance source inverters/converters. A general expectation was demonstrated in terms of the volume and size reduction by applying wide band gap devices; minimization and optimization of impedance source network parameters for the single-phase qZS inverter topology being used as an independent power system and submodule in CMI; novel control methods, especially the MPC to improve the system performance; and future applications for high-power renewable energy power conversion. A comparison of ZSI using traditional Si devices and silicon carbide (SiC) wide band gap devices is further illustrated, verifying the superiority of cooperating modern semiconductor technique. This chapter has mainly provided a technical insight into the future research and development of impedance source inverters/converters.

  • Z-Source/Quasi-Z-Source AC-DC Rectifiers

    Active rectifiers are attractive as an interface for ac-dc conversion for use in electric vehicle charging, because of their high efficiency and bidirectional operation. This chapter discusses the voltage-fed Z-source and quasi-Z-source rectifier, which improve the voltage boosting capability of the traditional voltage source rectifier, are immune to short-circuit of the phase legs, and are able to conduct both inverter and converter modes bilaterally. When analyzing the dc side, the rectifier bridge is equivalent to a current source. From simulation results of phase voltages and currents, it can be seen that unity power factor is obtained through the control method, in both inverter and rectifier modes. The quasi-Z-source rectifier was further taken as an example to illustrate their steady-state operating principles, dynamic modeling, control scheme, and simulation results, providing the fundamentals for the future development of such rectifiers.
