Abstract:

This project provides the experience of applying an advanced version of Spurious Power Suppression Technique (SPST) on multipliers for high speed and low power purposes. When a portion of data does not affect the final computing results, the data controlling circuits of SPST latch this portion to avoid useless data transition occurring inside the arithmetic units, so that the useless spurious signals of arithmetic units are filter out. Modified Booth Algorithm is used in this project for mul ....etc

NOVEL ACTIVE POWER FILTERS FOR HARMONICS SUPPRESSION



INTRODUCTION
CONCEPT OF HARMONICS
Harmonics can be defined as entities having a frequency in integral multiples of the fundamental frequency. This means, if we have a fundamental frequency of f Hz, the entities 2f, 3f, 4f, 5f etc. are called as harmonics. During the past decades many power electronic devices such as 6-pulse converters, variable speed motor drives, and other power electronic equipment for energy fl ....etc

ABSTRACT

This paper focuses on a shunt active filter based on the detection of harmonic voltages at the point of installation. The objective of the active filter is to attenuate harmonic propagation resulting from series/parallel resonance between capacitors for power factor correction and line inductors in a power distribution line. The active filter acts as a low resistor to the external circuit for harmonic frequencies, and it is installed on the end bus of the power distribution line, just like a 50 O terminator installed on the end term ....etc

This seminarsr provides the experience of applying an advanced version of our former spurious power suppression technique (SPST) on multipliers for high-speed and low-power purposes. To filter out the useless switching power, there are two approaches, i.e., using registers and using AND gates, to assert the data signals of multipliers after the data transition. The SPST has been applied on both the modified Booth decoder and the compression tree of multipliers to enlarge the power reduction. The simulation results show that the SPST implementat ....etc

In this seminar a method for wideband harmonic compensation is presented. The main circuit configuration of the system is shown in Fig. 2. The system compensates the low order harmonics using a simple computational control delay compensation method, while the high order harmonics are filtered with a small passive high pass filter. In the system the whole filtering band of the APF is utilized and the filtering performance is recovered with an HPF when the ability of the APF to filter harmonics effectively is impaired. This way the size of the pa ....etc

Abstract
This paper presents a simplified sinusoidal uninterruptible power supply (UPS) system. The proposed scheme includes features such as high power factor, low total harmonic distortion and good dynamic response at the ac output voltage. In addition, the scheme has the desirable characteristics of high efficiency, simple circuit and low cost compared with a traditional standalone multiple stages UPS with power factor correction. The paper also presents the circuit operation, the analysis and, experimental results of the proposed UPS sch ....etc
