The converter is in principle realized by inserting a Z-source impedance network to the dc-link of the otherwise voltage-buck only indirect matrix converter (IMC), formed by cascading a front-end current source rectifier and a rear-end three-level inverter together. Topology wise, the proposed converter is therefore not distinctly different. Rather, the focus is on its modulation control, whose hidden details, different from those of traditional IMC, must be unveiled before voltage buck-boost and sinusoidal input-output quantities can be produced simultaneously, together with a lower commutation count and narrow pulse avoidance. This theme of investigation is now pursued in the paper with the converter operational modes and optimal modulation possibilities discussed extensively to bring forth its attractiveness for ac-ac buck-boost energy conversion, as validated in simulation.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"145 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131694220","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}

Most of the previously reported linearizing techniques are not suitable when the reference input amplitude or operating frequency is large. In this paper, a dynamic linearizing modulator (DLM) for the boost converter is proposed, which transforms the open-loop converter into a linear amplifier with an operating frequency as high as one-fifth of the switching frequency. The modulator generates the duty by comparing the non-linear part of a boost converter dynamic equation with a sine wave reference voltage on a cycle-to-cycle basis. The technique exhibits superior audio-susceptibility due to the feed-forward of input voltage. The formulation, implementation, and verification of this technique are discussed. Experimental results show that the output voltage is able to track a large-signal reference input upto one-fifth the switching frequency.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115505039","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}

The paper proposes the matrix converter topology with three-phase grid input and five-phase variable voltage and variable frequency output. The control technique developed and presented in the paper is based on space vector approach. The paper presents the complete space vector model of the proposed matrix converter topology. The model suggests 215 total switching combinations which reduce to 243 states considering the imposed constraints, out of which 240 are active and 3 are zero vectors. However, for space vector PWM (SVPWM) implementation only 90 active and 3 zero vectors can be used. The SVPWM algorithm is presented in the paper.

For an increase in torque and efficiency in constant power region, the saliency ratio is increased more than initial model. The two points, 2000 rpm (rated speed) in the constant torque region and 4000 rpm (double rated speed) in the constant power region, are chosen for comparing the torque and efficiency with the initial model. The maximum torque control is composed of maximum torque per ampere (MTPA) control in constant torque region and flux weakening (FW) control in constant power region. In the optimal design process, the d- and q- axis inductances at each current angle are extracted by finite element method (FEM) for MTPA and FW control. The FEM is used to calculate the cogging torque. And then, radial basis function (RBF) and genetic algorithm (GA) are used. The results showed an increase in the efficiency and torque compare to the initial model, and also the cogging torque is decreased more than initial model.","PeriodicalId":161915,"journal":{"name":"2010 IEEE Energy Conversion Congress and Exposition","volume":"39 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114830449","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}
