Wu K. Switch-Mode Power Converters 2006 torrent

Textbook in PDF format

The book covers in depth the three basic topologies: step-down (buck, forward), step-up (boost), step-down/up (flyback); push–pull; current-fed; resonant converters and their derivatives; AC–DC power factor correction. Depending on the operating conditions, switch-mode power converters may operate either in continuous conduction mode (CCM) or discontinuous conduction mode (DCM). Under transient conditions, the operation of power converters may slide in and out of both modes. For closed-loop control of converters, two fundamental mechanisms, voltage-mode control or current-mode control, are generally employed. Current-mode control has been understood to offer superior performance. Current mode control is further subdivided into average-current control and peak-current control. While most switchmode converters utilize pulse-width modulation, resonant converters
use frequency modulation. In addition to the main operation mechanism, many supporting circuits are also needed to make power converters viable. These include switch drivers, error amplifiers, and feedback isolators
