Equations of State Variables of Electromagnetic Circuits in Engineering Education of MEMS-Specialists

It is proposed to form for the method of state variables of differential levels of electromagnetic circuits with branched electric and magnetic sub-circuits. Differential equations are formed in relation to independent variables: voltages of capacitors of ribs, currents of the chord of the graph of the electric sub-circuit and magnetic fluxes of the chord of the graph of the magnetic sub-circuit. The method of analysis is the basis for the construction of modern circuit and circuit-field mathematical models of electrical and electromechanical devices. In this case, the differential equations of these devices are written in the normal Cauchy's form, focused on the further application of numerical methods for integrating differential equations using computer calculating tools. The method of analysis has passed strict testing in real applied problems of electromechanics, power engineering, computerized automation systems. An example is added: differential equations of a saturated double-winding transformer with a capacitive load.
