  • WIDEBAND BALANCED FILTERS BASED ON MULTI&#x2010;SECTION MIRRORED STEPPED IMPEDANCE RESONATORS (SIRs)

    This chapter aims to study some implementations of wideband balanced bandpass filters based on multi‐section mirrored stepped impedance resonators (SIRs) and to provide guidelines for their design. Through the use of such resonant elements, it is possible to achieve wideband differential‐mode responses and an efficient common‐mode rejection by the selective introduction of transmission zeros for the common mode. The chapter also reports three filter examples, including an order‐5 and an order‐7 wideband filter, both based on 7‐section SIRs coupled through admittance inverters, and an order‐5 ultra‐wideband (UWB) balanced filter based on 5‐section SIRs and patch capacitors. In order to implement the balanced filters, the mirrored SIRs are alternated either with balanced quarter‐wavelength transmission‐line sections (acting as admittance inverters) or with series resonators (in balanced configuration) implemented by means of lumped elements (interdigital or patch capacitances and inductive strips).

  • Appendix C Proof of Stationary Behaviour of Mutual Impedance

    This appendix explains proof of stationary behavior of mutual impedance. A reason for relatively accurate results being possible with simple current approximations is that mutual impedance expression, is stationary with respect to small variations in currents on the antennas. This book covers aperture antennas, which include the main types of horns, reflectors and arrays as well as microstrip patches, reflect arrays and lenses. To provide more than a superficial treatment of arrays, the topic of mutual coupling is covered in greater detail than most similar books in the area.

  • Impedance Source Inverters

    The Z¿¿¿source/quasi¿¿¿Z¿¿¿source inverter (ZSI/qZSI), so called impedance source inverter, has attracted increasing interests due to a single¿¿¿stage power conversion with step up/down function, handling the DC voltage variations in a wide range without overrating the inverter, and allowing the switches on the same bridge leg turn on together. All of these can minimize system cost, reduce component count and cost, and improve system reliability. The operation principle and control methods of conventional ZSI/qZSI are presented. Also, the advantages and control of novel extended topologies, such as qZSI with Battery and qZSI based cascade multilevel systems are discussed. Impedance parameter design is addressed in detailed. This chapter offers a comprehensive and systematic reference for the future development of the high performance ZSI/qZSI.

  • 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.

  • 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.

  • Impedance and Admittance Formulas

    There are various types and configurations of cables as explained in Chapter 1. Those are categorized in general in two types: (1) single core coaxial (SC) cable, and (2) pipe-enclosed type (PT) cable. Also, there are (a) directly buried cable, (b) tunnel-installed cable, and (c) overhead cable. In this chapter, the impedance and admittance formulas of an SC cable and a PT cable, either underground or overhead, are described starting from the formulation of the impedance and admittance matrices (potential coefficient matrix). Then, a formula of each element is presented, and an approximate formula is explained. Also, examples of the frequency responses are demonstrated. Finally, EMTP subroutines Cable Constants and Cable Parameters which calculate the cable related parameters explained above is introduced.
