The various quantities which are introduced-such as current and potential and resistance-are summarized in Appendix A together with the symbols used to represent them, the unit associated with each quantity and the formula used to derive that unit from four fundamental or MKSA units....
One of the most important parts of the basic theory of electrical circuits is the chapter that refers to energy and power. Furthermore in various electrical circuits' applications such as communications systems, control systems, radio transmitter design, stereo amplifiers, renewable systems, the analys...
A self-consistent theory is given of ac and dc transport in disordered hopping systems. The method is an extension of an effective medium approximation and a Cayley tree formalism. The calculated dc and ac conductivity are compared with the results of computer simulations of R-hopping networks an...
Effective media theory was applied to measured AC composite permeability to extract particle magnetic properties and thereby anisotropy field, which increased by an order of magnitude from the bulk. Permeability decreased with particulate size. 展开 ...
Based on drift-diffusion equation and energy balance equation,a SiGe HBT DC and AC model was established.In addition,the velocity saturation effect,base and mitter bandgap narrowing effect and the recombination effect are included.Finally,the theory and mesa-type SiGe HBT experiment results were comp...
In general, the DC conductivity is due to the In such a composite of high NaTCNQ content, continuing percolation of carriers between conduction carriers are mainly composed of electrodes and reflects the most probable the intergranular hopping electron, intragran- hops. The AC conduction reflects ...

In the present investigation, instead of phase control applied to a dc-to-ac conventional converter with an inductor and a dc source at load side, here, discontinuous phase control switching is employed, in a novel dc-to-ac converter circuit topology where two pairs of inductors or reactors ...
The filters may have a common DC link and the shunt filter is controlled using the concepts of the instantaneous real and imaginary powers (p-q power theory). The series filter is controlled in such a way as to cancel the output voltage ripple of the rectifier. Digital simulation results ...
