In this paper, the partial element equivalent circuit (PEEC) model is applied to strip-lines analysis in high speed circuit design. The mathematical formulation of the PEEC model is derived. By using thin-film and quasi-static Green's function for strip-line structures, the details of the application of PEEC model to strip-lines are introduced, The computational results for parallel strip-lines are...
The paper presents design, modeling, control and implementation of a ldquolong-pulserdquo three-phase resonant converter. A DQ equivalent circuit model of the resonant tank system is established first. Based on that, a model of the whole power supply and a state space multivariable feedback control has been developed. The soft switching, zero current switching (ZCS), is achieved by combining frequency...
This paper presents the most recent progress in deep research to the large-signal modeling technique for current-mode-controlled SMPS modules. The small-signal analysis to the lower-frequency power transfer model is carried out and the conclusion is obtained that the power stage model does not lose any small-signal information so the proposed large-signal simulation scheme is able to be used in small-signal...
Existing power diode models in most time-domain circuit simulators cannot accurately present the reverse recovery characteristics of actual diode devices with fast simulation speed. Ma-Lauritzen model is a relatively simple solution for modeling the reverse recovery of diode with reasonable accuracy but so far little result has been reported on the methodology and process for applications in circuit...
This paper proposes a universal approach (model) to deal with current mode controlled power modules while investigating large-signal interactions among subsystems in a distributed dc power system. By establishing a family of power stage models that embody nonlinearity to an algebraic operation block and keeping all components along in the external feedback control loops staying in simulation, simulation...
