optimization based Steady State Analysis of three phase self excited induction generator
IEEE Transactions on Energy Conversion, 2000Co-Authors: A L Alolah, Majeed A S AlkanhalAbstract:This paper presents a Steady State Analysis of a three phase self-excited induction generator. The problem is formulated as a multidimensional optimization problem. A constrained optimizer is used to minimize a cost function of the total impedance or admittance of the circuit of the generator to obtain the frequency and other performance of the machine. Classic gradient optimizers are used for this purpose as "fmin" and "constr" routines built in basic Matlab. Unlike the other reported methods of Analysis, the same equation is to be solved irrespective of the unknown parameters. The Analysis presented is validated by experimental results.

Steady-State Analysis of self-excited induction generators
IEEE Power & Energy Magazine, 1994Co-Authors: T.f. ChanAbstract:Two solution techniques for the Steady-State Analysis of a self-excited induction generator (SEIG) are presented in this paper. The first technique employs a novel parameter elimination procedure to yield a 7th-degree polynomial in the per-unit frequency, numerical solution of which enables the performance of the SEIG to be determined. The second technique employs symbolic programming for the derivation and solution of the the high-order polynomial. The symbolic programming technique is further extended to the Analysis of a voltage compensated SEIG using long-shunt connection. Very good agreement between experimental and computed results have been obtained on a 2 kW laboratory machine. >

Steady-State Analysis of PWM DC-to-DC regulators
IEEE Transactions on Aerospace and Electronic Systems, 2003Co-Authors: Nicola Femia, G. Spagnuolo, Massimo VitelliAbstract:A new method for Steady-State Analysis of pulsewidth modulation (PWM) hard-switching DC-to-DC regulators is presented. The power stage and the feedback control circuit are analyzed as two interconnected blocks. The intersection of their open-loop DC Steady-State characteristics with the ramp voltage provides a guess candidate Steady-State solution (CS). An iterative process is used to validate it as true Steady-State solution (TS) when the bias conditions of switching devices (SDs) are fulfilled everywhere in the switching period.

Steady-State Analysis of soft-switching converters
IEEE Transactions on Circuits and Systems I-regular Papers, 2002Co-Authors: Nicola Femia, G. Spagnuolo, Massimo VitelliAbstract:Steady-State Analysis of soft-switching converters is discussed in this paper. Finding the Steady-State solution of soft-switching converters by means of start-up transient simulation may involve onerous computations and convergence failure, because of the mix of fast and slow natural frequencies determined respectively by the presence of soft-switching Lr-Cr cells elements and bulky L-C filter elements. The numerical method proposed in this paper shows high reliability and fast convergence, thanks to the adoption of an interval Analysis based technique for the detection of commutations and of a compensation theorem based technique for the Analysis of commutations. Some examples of Steady-State Analysis of two dc-dc converters, an inverter and a power factor corrector are presented to highlight the good performances of the simulation algorithm.
