  • 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.

  • Z-Source Matrix Converter

    There are two types of ac-ac conversion systems, the traditional ac-dc-ac converter and the matrix converter (MC). The traditional ac-dc-ac converter consists of a pulse width modulation (PWM) boost rectifier and a PWM inverter with dc-link bus. This chapter presents an updated overview of the different Z-source matrix converter topologies including the Z-source indirect matrix converter (ZSIMC), with its all-silicon and not all-silicon configurations, and also the Z-source direct matrix converter (ZSDMC). A new control method has been proposed to increase the operating voltage range of an indirect matrix converter based motor drive, while at the same time guaranteeing unitary input power factor. The QZSMC topologies overcome the voltage gain limitation of the traditional MC and achieve buck and boost conditions with a reduced number of switches, therefore achieving low cost, high efficiency, and reliability compared to the back-to-back converter.

  • Multipulse Diode Rectifiers

    This chapter focuses on the separate???type multipulse rectifiers, where each of its six???pulse rectifiers feeds a separate DC load. The main feature of the multipulse rectifier lies in its ability to reduce the line current harmonic distortion. This is achieved by the phase???shifting transformer, through which some of the low???order harmonic currents generated by the six???pulse rectifiers are canceled in the transformer primary winding. The multipulse rectifier has a number of other features. It normally does not require any load commutated (LC) filters or power factor compensators, which leads to the elimination of possible LC resonances. The multipulse diode rectifiers can be classified into two types: series???type multipulse rectifiers, where all the six???pulse rectifiers are connected in series on their DC side and separate???type multipulse rectifiers, where each of the six???pulse rectifiers feeds a separate DC load.

  • POWER ELECTRONICS

    In a circuit???oriented simulation environment, there are three levels of modeling: component level, circuit level and system level. A system???level simulation can merge the interaction of different modules in a system, for example, a converter, a controller, source, and load. A very appropriate level of circuit???level modeling must be chosen to incorporate the functionality and large signal behavior of switching converters, fast inner control loops, and fundamental power electronic switch operation. The PSIM circuit simulator approaches the idealized switching of semiconductors instead of detailed physical models with a good degree of analog and digital circuits required for designing circuits. A simple circuit that can be studied in a circuit simulator is a half???wave rectifier, because it can be used for cross???examination of exact mathematical calculations with their simulations in a circuit simulator as well as their numerical computation using a platform such as MATLAB.

  • Transformerless MV Drives

    This chapter focuses on the development of medium???voltage (MV) drives without the need of isolation or phase???shifting transformers. It analyses the common???mode (CM) voltage issue in the MV drive, and discusses mitigation methods for the reduction or elimination of CM voltages. The chapter presents principle and realization of transformerless voltage source converter (VSC) and current source converter (CSC) fed MV drives. To develop a multilevel VSC fed MV drive without requiring isolation transformers, three methods can be generally employed: elimination of the CM voltages with the reduction of CM voltage scheme 2 (RCM2), suppression of CM voltage by CM filters, and combined method of the CM filters and reduction of CM voltage scheme 1 (RCM1)/RCM2 schemes. With the neutral point of the stator winding grounded, the CM voltage produced by the rectifier and inverter is applied to the neutral of the transformer winding.

  • Dynamic Average Modelling of Rectifier Loads and AC-DC Converters for Power System Applications

    This chapter presents an overview of dynamic average-modelling of front-end diode rectifier loads and pulse width modulation (PWM) AC-DC converter systems. It also presents a detailed analysis with an overview of all possible modes of operation from open-circuit to short-circuit conditions. The chapter discusses the basic approaches for developing the AVMs. Three selected average-value models (AVMs) are utilized in extracting steady-state operational characteristics of the rectifier system, followed by a comparative analysis of the AVM dynamic orders. The chapter compares the small-signal input/output impedance characteristics predicted by different models. It examines the transient performance of the AVMs for various operating conditions including light and heavy loading conditions, discontinuous and continuous modes, as well as balanced and unbalanced AC side. Finally, the generalization of the analyses is considered for high-pulse-count converters using an example six-phase topology.
