    The objective of this course is to provide the student with information about the latest technology used in Panasonic’s new line of microwave ovens. Upon successful completion of this course, the student will learn the differences between the high voltage circuit used in most microwave ovens, and the Inverter technology used in this line of Panasonic microwave ovens. The student will also have a better understanding of the new features and the function of the major components of the microwave oven. Язык: английский

    Alexander and Sadiku's fifth edition of Fundamentals of Electric Circuits continues in the spirit of its successful previous editions, with the objective of presenting circuit analysis in a manner that is clearer, more interesting, and easier to understand than other, more traditional texts. Students are introduced to the sound, six-step problem solving methodology in chapter one, and are consistently made to apply and practice these steps in practice problems and homework problems throughout the text. A balance of theory, worked examples and extended examples, practice problems, and real-world applications, combined with over 468 new or changed homework problems for the fifth edition and robust media offerings, renders the fifth edition the most comprehensive and student-friendly approach to linear circuit analysis. This edition retains the Design a Problem feature which helps students develop their design skills by having the student develop the question as well as the solution. There are over 100 Design a Problem exercises integrated into the problem sets in the book. Автор: Charles K. Alexander, Matthew N. O. Sadiku Год издания: 2012 Язык: английский

    This updated version of its internationally popular predecessor provides and introductory problem-solved text for understanding fundamental concepts of electronic devices, their design, and their circuitry. Providing an interface with Pspice, the most widely used program in electronics, new key features include a new chapter presenting the basics of switched mode power supplies, thirty-one new examples, and twenty-three PS solved problems.

    This work presents different novel gate drive unit (GDU) concepts for IGBT and reverse conducting IGBT (RC-IGBT). They have been experimentally tested with medium voltage class IGBT modules (1200...1700V/650…1400A) and a RC-IGBT module (1200V/200A). The switching behaviour of the RC-IGBT was investigated, and a new trigger pulse pattern to drive the RC-IGBT was developed, designed and implemented. The experimental results showed that the switching losses were reduced by 20% in the RC-IGBT compared to the switching losses of a standard diode. Two novel schemes are introduced to estimate the collector current through the IGBT, based on the measurement of the voltage across the internal stray inductance of the IGBT module. Furthermore, a GDU concept was derived to balance the on-state collector currents of parallel-connected IGBTs, reducing the current imbalance to 5%. Also, a new fast short circuit protection method (FSCP) for IGBT modules was developed, designed and implemented in another GDU, allowing turning-off the considered IGBT in less than 1?s, reducing the IGBT stress. Another scheme implemented in a GDU features an improved gate current switching profile of the IGBT, which reduces the switching losses by 25% compared to the standard switching method. In order to reduce the conduction losses, a GDU with an increased turn-on gate-emitter voltage (larger than 20 V) was investigated. In the investigated IGBT, the on-state losses were reduced by 18% when a gate-emitter voltage of 35V is used compared to when a gate-emitter voltage of 15V is used. All these new GDU concepts have been implemented with a simple and inexpensive electronic circuitry, which is an important feature for a possible industrial implementation Автор: Ignacio Lizama Язык: Английский Год издания: 2016

    ON Semiconductor is committed to providing optimal solutions for any given power supply requirement. Our commitment is reflected in providing design guidance in choosing between many options for topology and components. In this handbook we have attempted to provide a detailed comparison between various options for PFC implementation while keeping it in the context of total system requirements. As new technologies and components are developed, the balance of choice may shift from one approach to the other, but the methodology used in this handbook will remain applicable and provide a means for the power supply designer to arrive at the best choice for a given application.
