The first adaptive scheme is to simultaneously estimate on-line stator and rotor resistance of induction motor with speed-sensor. The second adaptive scheme is to simultaneously estimate stator resistance and rotor speed in sensorless induction motor drives. These two methods are based on adaptive control theory of model reference adaptive system (MRAS) approach with Luenberger observer in a similar way. And the stabilities of the observers with both adaptive estimation schemes in vector control of induction motors are proved by the Lyapunov's theorem. Furthermore, the methods have been compared with the classical adaptive schemes based on the integration algorithms. And in fact, the proposed methods are generalization of the integration adaptive algorithms. Finally the feasibility of the schemes are verified by simulation","PeriodicalId":210889,"journal":{"name":"2006 IEEE Workshops on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132422767","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper proposes a modeling approach for the analysis of multiple single-phase PFC converters, achieved by aggregating them into a single equivalent three-phase load. This equivalent model may then be readily converted into the d-q-0 synchronous frame where formerly time-varying state variables become DC quantities in steady state. From the resultant average model small-signal analysis may then be easily performed by either analytic or numerical methods. This paper presents the complete derivation of the proposed d-q-0 average model for multiple single-phase PFC converters, using time-domain simulations for verification, exploring as well its small-signal analysis capability by studying the converters input impedance on all three d-q-0 channels. From these results the excellent performance and great usefulness of the model is verified","PeriodicalId":210889,"journal":{"name":"2006 IEEE Workshops on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115866580","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It skips analysis of several switching cycles and considers the cycles by using, for example, the backward Euler or the trapezoidal type algorithms. It is more accurate than the averaging method because it considers switching ripples and it is still efficient. However it has been proposed only for a non-autonomous system. This paper proposes a new extended envelope following method which can also analyze an autonomous system which is typical in the power electronics field. It is extended by introducing a switching condition concept to the original form and the EF and switching conditions are solved simultaneously. In the numerical process, a Jacobian matrix is evaluated where switch timing sensitivities are considered.

First, the placement of poles and zeros is defined from LCOs at the corner frequency of the power stage. Then, the gain of the PID compensator is found from the oscillations occurring at the desired crossover frequency of the system.

The simulations were usually aborted due to numerical convergence problems. This has been overcome by rearranging the elements of the equivalent circuit of the coupled inductor so as to place every inductance in series with a resistance. Discrepancies between the simulation and experiment have been categorized as follows: (i) coupling factors significantly influence the shapes of the secondary current waveforms and steepness of the slope after a switch transition; (ii) the representations of winding and core losses affect only the losses and not the shapes of the waveforms; (iii) the magnetizing inductance determines whether the converter operates in the continuous or discontinuous current mode","PeriodicalId":210889,"journal":{"name":"2006 IEEE Workshops on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114333219","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is difficult to diagnose a multilevel-inverter drive (MLID) system using a mathematical model because MLID systems consist of many switching devices and their system complexity has a nonlinear factor. Therefore, a neural network (NN) classification is applied to the fault diagnosis of a MLID system. Multilayer perceptron networks are used to identify the type and location of occurring faults. The principal component analysis (PCA) is utilized in the feature extraction process to reduce the NN input size. A lower dimensional input space will also usually reduce the time necessary to train a NN, and the reduced noise may improve the mapping performance. The output phase voltage of a MLID can be used to diagnose the faults and their locations. The reconfiguration technique is also proposed. The effects of using the proposed reconfiguration technique at high modulation index are addressed. The proposed system is validated with experimental results. The experimental results show that the proposed system performs satisfactorily to detect the fault type, fault location, and reconfiguration","PeriodicalId":210889,"journal":{"name":"2006 IEEE Workshops on Computers in Power Electronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-07-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123497770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
