This handbook provides in a single place all the essential information
needed in the practical switching mode power supply (SMPS) design in an
easy-to-use format. It may be as useful to the experienced designer as
it will to the recent engineering grad, a student, and a hobbyist. The
key covered topics: - Main practically used isolated and non-isolated
converter topologies, including active PFC; - Power transformer and
inductor design and estimation of the losses; - Feedback control loop
relationships including transfer function with TL431; - Miscellaneous
design and analysis topics, such as MOSFET switching time and losses,
capacitance calculation for transient response, PCB trace
characteristics, and little-known empirical equations. The covered
converter topologies are: - Buck - Fly-Buck(TM) - Boost - Buck-boost
(non-isolated flyback) - SEPIC - CCM and DCM isolated flyback - Forward
(including active clamp forward) - Half-bridge - Phase shifted full
bridge with current doubler - LLC - CCM and DCM PFC boost For each
covered topology, the book provides power plant diagram, brief operation
principal, basic waveforms, DC transfer function with efficiency factor,
voltage and current stresses in switches and rectifiers, magnetics
equations, DC and AC components of the currents in all coils, and often
overlooked RMS currents in input and output capacitors. The analysis is
provided for worth case input voltage. Note that this is not a textbook
for learning power electronics. This handbook is for those who know the
electronics basics and need a quick reference and practical engineering
equations. It should speed up your design by saving time that would
otherwise be spent on deriving equations and searching the literature,
not to mention on re-spinning the board because of incorrectly selected
magnetics, underrated components, or improperly sized PCB traces.
