To

All electrical and electronic engineering professionals

R. P. Deshpande has more than 40 years of experience in the capacitor technology sector. He has worked as a consultant with capacitor manufacturing organizations, both growth-oriented start-ups and established companies, to help them achieve leading industry positions. Throughout his career, Mr. Deshpande has pioneered the development of many capacitor products, technologies, processes, and related applications. His recent research has focused on ultracapacitors, and his work on the use of capacitors for energy storage and alternative energy is widely recognized. Mr. Deshpande is a Fellow of the Institution of Engineers (India) and an electrical engineering graduate of the Indian Institute of Technology, Mumbai.

The role of capacitors to help improve grid efficiency and reliability can hardly be overstated. By producing reactive power, capacitors compensate for the reactive power consumption of electrical motors, transformers, etc. This results in more stable power grids with increased transmission capacity and reduced losses. Though an elementary electrical device, its applications in emerging fields, such as smart-grids and renewable energy, have underscored capacitors versatility and business value.

The book Capacitors is an authoritative account about capacitors and related developments. Mr. Deshpandes deep theoretical knowledge and an envious industry experience provide for ample academic treatment about the subject matter and, an evolutionary perspective of capacitor technology.

The book covers capacitors for both electrical and electronic fields in sufficient details, including latest development trends. Possibility of using ultracapacitors for grid stability and power quality through active power management are very interesting. The new breed ultracapacitors are seen to have opened many new avenues for capacitor applications.

Importantly for electrical or power engineering students, as also for electronic engineers, the book brings forward capacitors diverse business applications and this, in my opinion, could prove inspirational for many to choose it as a career option. As a reference guide, this work is equally valuable to young and mid-career professionals and as also to entrepreneurs connected with capacitors.

I recommend this book to anyone who wants to learn about the exciting field of capacitors, and urge colleges and universities to make it available through their libraries.

Capacitor, a basic component in electrical and electronic engineering, engulfs varied functions in electronic circuits, automobiles traction, mobiles, motors and power supplies, to mention a few. The author, in this book, brings together up to date information on most present-day capacitors. This book is the outcome of vast experience of the author in the capacitor industry.

The strength of this book lies in the comprehensive technical data and latest manufacturing practices relevant to the users in the capacitor industry. The richness of the book lies in its wide coverage of the subject matter, starting with a brief history of capacitors, their types, as also suitability for different applications. It dwells at length on basics like dielectrics, electrodes, construction and manufacture of capacitors and describes the latest trends and developments taking place in capacitor fields. All types of dielectrics and capacitors including XY safety capacitors are covered. Several applications of capacitors in power electronic circuits, automotive industry, power factor management, harmonic control are discussed in separate chapters.
