Abstract :
This book helps the reader master the switch-mode concept in pulse-width modulation (PWM) and resonant power supplies and then emphasizes statespace modeling in a deep way, seldom seen in power electronics literature. It explains how to obtain the converter open-loop transfer functions for dc voltage gain, ac line-to-load voltage, and duty cycle-to-output voltage, comparing two approaches: average state-space modeling and average switch modeling. Besides presenting the transfer functions for the buck, boost, buck??boost, Sepic, and Zeta converters in CCM, this book also obtains their transfer functions in DCM, showing the dissimilar dynamics regarding CCM while also presenting the transfer functions for the PWM switch, the zero-current resonant switch (ZCS), the zero-voltage resonant switch (ZVS),and the ZCS and ZVS buck, boost, andbuck??boost quasiresonant converters (QRCs), making this book truly unique.
