T. M. Blooming Conference Record Cement Industry Technical Conference, 2005., 2005
Adding power factor correction capacitors provides well-known benefits to industrial plants. These benefits include power factor correction, voltage support, and release of system capacity. Engineering judgment must be used, however, when applying capacitors in power systems with excessive harmonics and/or transients. Capacitors might not survive long in such environments if they are improperly applied. Capacitors are also known to cause ...

Power factor correction (PFC) converters have become the norm in almost all electronic systems. Most high-frequency power factor correctors use resistor emulation to achieve a near-unity power factor and a small line current distortion. This technique requires forcing the input current with an average current mode control to flow the input voltage. Stability of this system is discussed by using ...

In chapter 5 we move on to discuss AC-DC architectures for power conversion. Power Factor Correction and Pulse Width Modulation architectures and circuits for offline power conversion, as well as associated regulatory and technical trends are covered in the first part of the chapter. In the second part AC adapters for portable appliances are covered.

This chapter presents the detailed analysis of three boost???type pre???regulators commonly used for power factor correction in single???phase rectifiers: the single???switch basic boost, the two???switch asymmetric half???bridge boost and the interleaved dual???boost topology. The mathematical modeling approach is also illustrated and applied to the first two topologies. It can be systematically extended to the third one. On the basis of the obtained models, control algorithms were then developed and implemented. The reported simulation or experimental results show the effectiveness of these converters associated to their respective control systems, and validate the theoretical issues made out through the chapter.
Shunt capacitors can be used to provide reactive power to inductive loads, thereby raising or correcting the power factor. Three-phase capacitor banks can be connected in delta, wye, or grounded wye. The optimal configuration depends on whether the system is grounded or ungrounded, fusing considerations, and concerns about harmonics. Energizing a shunt capacitor is discussed by analyzing the voltage and current waveforms produced by the capacitor breaker closing operation. While harmonic currents and voltages present during capacitor switching can be potentially disrupting or damaging to power system components, they are transient in nature and are quickly damped by the system impedance. Harmonic currents and voltages are analyzed using symmetrical components. Shunt capacitors can create undesirable resonance conditions. Large transmission-class shunt capacitors are sometimes fuseless, relying on protective relays to de-energize them in the event of an internal fault or an excessive number of capacitor units shorted.

PSpice for Circuit Theory and Electronic Devices is one of a series of five PSpice books and introduces the latest Cadence Orcad PSpice version 10.5 by simulating a range of DC and AC exercises. It is aimed primarily at those wishing to get up to speed with this version but will be of use to high school students, undergraduate students, and of course, lecturers. Circuit theorems are applied to a range of circuits and the calculations by hand after analysis are then compared to the simulated results. The Laplace transform and the s-plane are used to analyze CR and LR circuits where transient signals are involved. Here, the Probe output graphs demonstrate what a great learning tool PSpice is by providing the reader with a visual verification of any theoretical calculations. Series and parallel-tuned resonant circuits are investigated where the difficult concepts of dynamic impedance and selectivity are best understood by sweeping different circuit parameters through a range of values. O taining semiconductor device characteristics as a laboratory exercise has fallen out of favour of late, but nevertheless, is still a useful exercise for understanding or modelling semiconductor devices. Inverting and non-inverting operational amplifiers characteristics such as gain-bandwidth are investigated and we will see the dependency of bandwidth on the gain using the performance analysis facility. Power amplifiers are examined where PSpice/Probe demonstrates very nicely the problems of cross-over distortion and other problems associated with power transistors. We examine power supplies and the problems of regulation, ground bounce, and power factor correction. Lastly, we look at MOSFET device characteristics and show how these devices are used to form basic CMOS logic gates such as NAND and NOR gates.
The phenomenon of building up a static charge when walking on a carpet illustrates the charge-storing abilities of human body capacitance. Many electronic devices, such as touch-screen displays, touch-sensitive switches, and computer touch pads make use of this property. Capacitors used in electric power applications are typified by the rectangular cans with one or two bushings. When the dielectric materials contain polarized molecules (dipoles), the polarization may be caused by field cancellation from the capacitor plates. In a simple DC circuit, capacitors can be charged through a resistor at an exponential rate. Power capacitors are used in electric power applications mainly for power factor correction and harmonic filters. Filter capacitors cause several electrical hazards, including the risk of electrical shock from a capacitor charged to a high voltage with a high stored energy. The capacitance of a cable is a distributed quantity-the longer the cable, the larger the capacitance.
