    Nonlinear electrical loads are shown to be the major source of wave distortion. These are generally highly efficient types of loads; thus their usage can be expected to grow, and wave distortions can be expected to increase. Hidden costs from such loads are identified. Conditions which can result in excessive distortions are described. A new method of monitoring wave distortions is presented. It i... View full abstract»

    A triggering method is discussed which is specifically designed for a traction drive consisting of a high-frequency alternator, a phase-controlled cycloconverter, and an induction motor. Because the motor operates with controlled slip the power-factor characteristics are known, and this is utilized to obtain cycloconverter simplification and to optimize machine sizes. Specific advantages over a co... View full abstract»

  • Computer Analysis of the Static Stiffness of SCR DC Feed Drives Used on NC Machine Tools

    Publication Year: 1979, Page(s):494 - 500
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (2259 KB)

    It is shown that the SCR dc feed drive stiffness depends upon the torque and speed of the motor. In particular, changing from continuous to discontinuous conduction in the armature circuit has a significant effect upon the drive stiffness. Analytic expressions for both static and dynamic stiffnesses are derived, and computer-calculated diagrams of the static stiffness are presented. The digital co... View full abstract»

    The main auxiliary phenomena are considered which arise in the drives using a frequency-controlled induction motor supplied by a three-phase bridge inverter as an actuator. Particularly, three quality indexes connected with these phenomena are taken into account and, for different drives, the commutating instants, which separately optimize the quality indexes, are determined. Lastly, a comparison ... View full abstract»

    State-space techniques are employed to derive an equivalent nonlinear recurrent time-domain model that describes the switched dc-dc converter behavior exactly. This model is employed effectively to analyze both large signal behavior by propagating the recurrence equation and matching boundary conditions through digital computation and small signal behavior by linearizing it about the equilibrium s...

    Generally, static var generators function as variable reactances (capacitive or inductive impedances) or controllable ac current and voltage sources. Possible methods of var generation and control by static thyristor circuits are reviewed, and new approaches are described in which power frequency changers (cycloconverters) are employed. Oscillographic recordings illustrate the operation and perfor... View full abstract»

    A new current-commutating method applying the action of the mutually coupled inductances is described and is termed the coupled reactor commutating (CRC) method. With this method a unique self-excited controlled current type inverter is constructed. The CRC inverter not only gives an efficient voltage adjustment function, but it also liberates men from the task of treating reactive powers. An exam... View full abstract»

    The reverse phase-controlled dimmer is an alternate method for varying the intensity of incandescent lights. Unlike conventional phase-controlled dimmers, the thyristors are triggered into conduction immediately following the zero crossing of the ac line rather than being delayed into the half-cycle. After an appropriate delay the silicon-controlled rectifiers (SCR's) are turned off by forced comm... View full abstract»
