Power electronics laboratory : theory, practice & organization

Power Electronics Laboratory: Theory, Practice & Organization has been written as a reference for theory of power / industrial electronics and it also provides relevant information for the development and organization of a well-equipped power electronics instructional laboratory. The book includes experiments on converters using new power electronic devices such as IGBTs, Power MOSFETs, etc. Useful information is provided in four appendices covering general instructions, commonly used ICs and devices employed in control and triggering circuits. With its up-to-date and balanced coverage of all important power electronic devices, the book is a rich source of information to instructors, teachers, manufacturers of Drives and laboratory incharges. It will prove a practical and necessary supplement to the main text for undergraduate, postgraduate and diploma students of electrical, electronics and telecommunication engineering
