About:
A revolution occurs in the paradigm within the power electronics area, replacing traditional ways of thought with a modern view of the control theory. Taking this approach, the authors begin their revolutionary quest in Numerical Control Theory for Power Electronics.
Often unnoticed, such as the air is for breathing, power electronics provide an instrumental means of transporting electrical energy from the source to the consumer. This critical domain is as essential as drinking water and breathing air in an uninterrupted process of energy transfer. Yet, there is a book that disputes the idea of conforming exclusively to the conventional analog control approach which was established for more than one hundred years.
The book, “Digital Power Electronics and Application”, is based on a solid theoretical foundation, describing various possible applications of them. The study which comprises about 400 pages is laid out carefully with close to 300 graphs to ensure comprehension. Using modern digital technology as power electronics control has been proven effective in this article, and it can overcome misconceptions like analog control in the right way.
Traditionally, power electronics have been analyzed through the lens of analog control theory, producing commendable results. However, these successes have inadvertently led to the misguided belief that analog control is the ultimate and final solution for Power Electronics. The authors challenge this misconception, emphasizing that mature control methods should not mark the end but rather the beginning of a new chapter for Power Electronics.
A fundamental aspect of this exploration is the meticulous examination of power transmission technology. AC and DC drive systems, acting as the conduits between electrical and mechanical energy, come under the scrutiny of the authors. These systems, collectively known as power supplies, operate through switching circuits that function in discrete states of on and off. The high-frequency semiconductor devices within these circuits enable the realization of high power rates, efficiency, cost-effectiveness, compact size, and elevated energy density.
An intriguing revelation emerges as the authors draw attention to the vast difference in size between a flat transformer operating at 250 kHz and a conventional transformer at 50 Hz, both handling the same power rate. The intermittent operation of switching circuits, operating periodically in states of on and off, challenges the traditional notion of constant energy flow. Instead, these circuits, along with transformers, facilitate power transfer by quantizing energy across specific storage elements, loading it in predefined sampling periods.
In essence, "Digital Power Electronics and Applications" redefines the landscape of Power Electronics. It invites readers to question conventional wisdom, encouraging a shift towards digital control methods. By dispelling the notion of a sunset in the knowledge of Power Electronics, the authors breathe new life into this critical field, ushering it into a future where the digital frontier reigns supreme.
