괜찮다고 말하지만 괜찮지 않은 너와 나, 우리가 안고 사는 우울. 그리고 그 감정이 가져온 마음의 병 우울증. 화제의 채널



Most industrial and consumer electronics are powered from a dc source whose voltage level is fixed in advance.



For examples, telecommunication electronics usually receive their input power from a 48V dc source and cellular phones operate with 3 V rechargeable batteries.



Meanwhile, circuits inside such equipment require several dc voltages that are different from the voltage level of the input source.



Accordingly, each equipment contains specially-engineered circuit blocks capable of changing the input voltage to another dc level, as required by the various internal circuits.



The process of changing the voltage level of a dc power source into another value is broadly referred to as the dc-to-dc power conversion.



The dc-to-dc power conversion is performed in many different ways, each with a distinctive circuit technique.



The most popular scheme is the dc-to-dc power conversion circuit employing the pulsewidth modulation (PWM) technique.



The dc-to-dc power conversion based on the PWM technique is called the PWM dc-to-dc power conversion. Circuitries designed for the PWM dc-to-dc power conversion are called PWM dc-to-dc converters



This book is primarily intended to be a textbook for undergraduate and first-year postgraduate students who are beginning to study power electronics focusing on the PWM dc-to-dc power conversion.



The book supplements existing textbooks with more dedicated treatments on the PWM dc-to-dc power conversion.



The book is also written as a reference book for engineers working in the area of modeling, analysis, and control of PWM dc-to-dc converters.
