Description du livre
This book introduces electric circuits with variable
loads and voltage regulators. It allows to define invariant relationships for
various parameters of regime and circuit sections and to prove the concepts
characterizing these circuits. The book presents the fundamentals of electric
circuits and develops circuit theorems. Generalized equivalent circuits
are introduced. Projective geometry is used for the interpretation of changes
of operating regime parameters. Expressions of normalized regime parameters and
their changes are presented. Convenient formulas for the calculation of
currents are given. Parallel voltage sources and the cascade connection of
multi-port networks are described. The two-value voltage regulation
characteristics of loads with limited power of voltage source is considered.
This second edition is extended and contains additional chapters on circuits with
non-linear regulation curves, circuits with non-linear load characteristics,
concepts of power-source and power-load elements with two-valued
characteristics, quasi-resonant voltage converters with self-limitation of
current as well as the similarity of characteristics of converters and
electronic devices.
This book is useful to engineers, researchers and
graduate students who are interested in the basic electric circuit theory and
the regulation and monitoring of power supply systems.
