Power Electronics is the technology associated with efficient conversion, control and conditioning of electric power from its available input into the desired electrical output form. The field of the book is concerned of electrical power processing using electronic devices the key component of which is a switching power converter.
Power electronics has found an important place in modern technology being a core of power and energy control. Almost all the new electrical and electromechanical equipment contain power circuits. The power levels encountered in this field range from less than one watt in supplies for the battery-operated portable equipment to tens, hundreds, or thousands of watts in power units of office equipment, kilowatts to megawatts in variable-speed motor drives, approaching megawatts in the rectifiers and inverters that interface the local transmission lines with the high power systems.
The impact factor of journal provides quantitative assessment tool for grading, evaluating, sorting and comparing journals of similar kind. It reflects the average number of citations to recent articles published in science and social science journals in a particular year or period, and is frequently used as a proxy for the relative importance of a journal within its field. It is first devised by Eugene Garfield, the founder of the Institute for Scientific Information. The impact factor of a journal is evaluated by dividing the number of current year citations to the source items published in that journal during the previous two years.
