Available in PDF, EPUB and Kindle. Book excerpt: Nowadays the life cost more getting higher and higher. People more consider every dollar that they spend in their daily life. The price of gasoline more getting higher every year, this also make the life cost for each family increase. The price of electricity also increases because of the increase gasoline price. The people should spend their money with efficiently to make sure that the money that they spend is totally useful. There have two methods to save the electricity usage; the first one is using the electricity energy with smart, for example when the air-conditioner is not used it should turn off. The second is using the power factor correction technique, but this method just for inductive load such as air-conditioner, washing machine and refrigerator. The inductive load running causes the leading power factor, means the current that used is more and not totally used. To overcome this problem the reactive component is added, the capacitor is added to improve the power factor and also reduce the current that transfer to the inductive load. The microcontroller (PIC) is use as a control element that switching the capacitor to the power line. The sensor is place at the power line to giving the signal to the microcontroller, microcontroller analyze the signal that feed from the sensor. Microcontroller execute the instruction depend to the signal that giving.

This book was released on 2015-05-21 with total page 96 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the power quality of the ac system has become great concern due to the rapidly increased numbers of electronic equipment, power electronics and high voltage power system. Most of the commercial and industrial installation in the country has large electrical loads which are severally inductive in nature causing lagging power factor which gives heavy penalties to consumer by electricity board. This situation is taken care by PFC. PFC is the capacity of absorbing the reactive power produced by a load. In case of fixed loads, this can be done manually by switching of capacitors, however in case of rapidly varying and scattered loads it becomes difficult to maintain a high power factor by manually switching on/off the capacitors in proportion to variation of load within an installation. This drawback is overcome by using an Automatic Power Factor Correction panel. This book focuses on the design and implementation of power factor correction using PIC micro-controller chip, determine the power factor of the loaded power system, and generate proper action to calculate and to add sufficient capacitor.

Available in PDF, EPUB and Kindle. Book excerpt: The novel power factor correction system described here is an improvement over existing ones because it reduces the VAR's with no switching transients, continuously; i.e., without the customary VAR-jumps that result from the usual capacitor-switchings. Work on this concept was begun in the early 1980's by Mr. Frederick Rohatyn. The invention was granted a U.S. Patent (No. 4,672,298) in June 1987. Mr. Rohatyn continued his experiments for four year's following issuance of the patent. During that time, he built several prototypes in order to develop a practical realization of his idea. The invention was evaluated technically by the U.S. Department of Commerce, National Institute of Standards and Technology (NIST), resulting in very favorable recommendations. In the invention, the compensating reactive power is generated by a linear capacitor. A transformer is connected in series with the capacitor. The voltage applied to the capacitor terminals can be varied from zero to a maximum level. This is done by supplying the primary winding of the series transformer from a variable auto-transformer. This feature permits continuous variation of the reactive power generated by the capacitor. Based on the results of this study, the industrial partner intends to develop a line of production models and market them to power management companies worldwide.

Book Synopsis Power Factor Improvements in Domestic Loads Using PIC Microcontroller by : Abhinav Sharma
Download or read book Power Factor Improvements in Domestic Loads Using PIC Microcontroller written by Abhinav Sharma and published by LAP Lambert Academic Publishing. This book was released on 2015-08-26 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Power factor correction (PFC) is a technique of counteracting the undesirable effects of electric loads that create a power factor that is less than one. Power factor correction may be applied either by an electrical power transmission utility to improve the stability and efficiency of the transmission network or correction may be installed by individual electrical customers to reduce the costs charged to them by their electricity supplier. In order to improve transmission efficiency, power factor correction research has become a hot topic. Many control methods for the power factor correction (PFC) have been proposed. This research work describes the effect of combination of loads on power factor of microcontroller based power system and also described the design and analysis of a power factor correction using PIC microcontroller chip. This involves measuring the power factor value from the load using PIC and proper algorithm to determine the sufficient firing angle to trigger the TRIAC in order to compensate excessive reactive components, thus bringing power factor near to unity. In this research work, four experiments were conducted.

Available in PDF, EPUB and Kindle. Book excerpt: The input current harmonics of the rectifier is very harmful. Not only does it reduce the power factor of the AC-DC converter and cause a lot of electrical energy loss; but also it will damage other devices and pollute the line power system. Measures should be taken to reduce these harmonics. The commonly used method is to design an effective PFC circuit for the AC-DC converter. In this book, a boost APFC circuit will be discussed in detail. It can work satisfactorily from full load to half load scope. The detailed design process will be described for this project, including topology choice, theoretical calculation of the main components values, the determination of the main components for this circuit, circuit simulation and experimental verification. According to the schematic design and the simulation revision, a test prototype is built to verify the performance. Several tests are implemented and the final experimental results indicate that this circuit design can satisfy the project specification and it is feasible for this project. As a reference book, it is suitable for electrical engineers and experts to check when they develop relevant power electronics products.
