摘要:
AbstractRealizability conditions of periodic waveforms in passive switched circuits are presented. Formulae for an identification of state matrices in switched circuits are derived. As input data, time functions of excitation and response are chosen. Six general transformer structures of 1‐port thyristor converters have been obtained as a result of the synthesis method. The synthesis methods presented can be applied to create new thyristor and transistor arrangements, particularly thyristor compensator

摘要:
AbstractAs an extension to the breakpoint hopping algorithm developed in reference 1, the algorithm presented in this paper efficiently solves the d.c. problem for finding the d.c.operating point(s)and for tracing thedriving‐pointandtransfer characteristicsof an extremely broad class of non‐linear resistive circuits. In particular, bipolar and MOS transistor circuits are included. A user‐friendly C program has been written to implement this algorithm where the input format for describing the circuit is compatible with the SPICE pr

摘要:
AbstractThe paper deals with the phenomenon of coupling of several sinusoidal oscillators. The oscillators are arranged in a ring, and each oscillator affects its next neighbour in the ring. The coupling is unilateral and its main effect is due to variations in phase differences between neighbouring oscillators. The simple approach to the treatment of the behaviour of the coupling and the relative simplicity of the models of oscillators participating in the system enable an analytical solution of the problem to be found without a need to resort to complicated approximate methods. The results are supported by computer simulations. Several modes of dynamic behaviour of the system are identified. The number of possible modes increases with the number of oscillators in the ring. The paper concludes by demonstrating that the present results possess a potential of being useful in analysing some technological and natural systems.

摘要:
AbstractThis paper describes an efficient approach to the simulation and exact sensitivity evaluation of multi‐coupled cavity filters. The approach uses sensitivity formulae for such responses as input or output reflectron coefficient, return loss, insertion loss, transducer loss, gain slope and group delay, which are derived for a two‐port equivalent of a general network described by its symmetrical impedance matrix. The formulae are specialized to the case of multi‐coupled cavity filters, using a filter model which takes into account many non‐ideal factors such as losses, frequency dependent coupling parameters and stray couplings. The formulation also treats synchronously or asynchronously tuned structures in a unified manner. Explicit tables of first‐ and second‐order sensitivities w.r.t. all variables of interest, including frequency, are presented. Three problems of significant practical value in manufacturing of multi‐cavity filters are solved with the direct application of our formulae. A 10th‐order filter is considered for all three cases. The first case is simultaneous optimization of the amplitude and delay responses to obtain a self‐equalized filter. The second case is accurate prediction of the responses for a lossy filter by simulating a lossless filter. The third case involves parameter identification of the filter from simulated measurements
