This ebook introduces electrical circuits with variable so much and voltage regulators. It permits to outline invariant relationships for varied parameters of regime and circuit sections and to end up the ideas characterizing those circuits. Generalized similar circuits are brought. Projective geometry is used for the translation of adjustments of working regime parameters. Expressions of normalized regime parameters and their alterations are provided. handy formulation for the calculation of currents are given. Parallel voltage resources and the cascade connection of multi-port networks are defined. The two-value voltage rules features of lots with restricted strength of voltage resource is taken into account. The booklet provides the basics of electrical circuits and develops circuit theorems. it's priceless to engineers, researchers and graduate scholars who're drawn to the elemental electrical circuit conception and the legislation and tracking of strength offer systems.

These expressions contain six normalized values. If regimes differ, we have the set of twelve different values. On the other hand, the normalization by the maximum load currents I1M ¼ y0N ðV0 À V1 Þ, I2M ¼ y0N ðV0 À V2 Þ leads to the reciprocal components I2 =I1M ; I1 =I2M . These components raise a number of normalized values. Therefore, the shown examples of the formal normalization do not allow comparing the regimes of different systems. 1 Volt Characteristics of an Active Two-Port Let us consider the features of an active two-port with two load conductivities YL1 ; YL2 in Fig.
