In this paper, the load neutral point voltage is modeled. Two factors influencing the load neutral point voltage are revealed, which are the switching states and the ratio of neutral inductance to phase inductance. Then, the load neutral voltage is analyzed. Sixteen switching states can be grouped into four classes, and each class is with the same load neutral point voltage. Switching states of the first and the second class come to the minimum valve of zero with the special ratio of k. Thirdly, three methods to mitigate the load neutral point voltage are proposed, and the benefit and the limitation of each method are analyzed. Finally, the proposed methods are verified by simulation and experiment.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126086486","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}

In this paper, the EVT system simulation model including the models of DMPM, internal combustion engine (ICE) and controller, is built. Base on this model, the dynamic process of the system such as the ICE's startup and stop, are analyzed. Simulation results show that there is an impact torque acting on the outer motor of DMPM at the moment of ICE's startup or stop, which should be avoided by the mechanical decoupling control and control method of ICE's startup. The experiment test rig is built, the method of mechanical decoupling control and the control method of ICE's startup is implemented during the experiment.

Because of the low work frequency, the optimal unsymmetrical PWM method requires optimizing each independent switch angle in order to achieve good control effect, and it needs to solve the nonlinear equations on-line inevitably to obtain the switch angle. A new algorithm by combining the predominance of the Newton and homotopy algorithms is proposed, which can effectively realize switch angle on-line computation with relative high convergence rate. At last, this paper validated the real-time performance and the effectiveness of the switch angle algorithms on the experimental platform with the control core of TMS320F2812.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"65 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121473771","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 switching devices in the proposed converter are operated by soft switching with a new partial resonant circuit. The partial resonant circuit is designed to replacement of an energy storage inductor and a snubber circuit used in a conventional buck-boost converter, and then the configuration of the proposed converter is simplified. The switching control technique of the converter is also simplified for the switches to drive in a constant switching frequency. The results are that the switching power loss is very low and system efficiency is high. In addition, the output voltage of the converter is regulated by PWM control technique, and the discontinuous current flowing into the resonant inductor of the converter makes to simplify control method and control components. In comparison with the conventional buck-boost dc/dc converter, some simulation results on computer and experimental results are confirmed the validity of analytical results of the proposed converter.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"48 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116557885","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}

Instead of the switching table and hysteresis controllers in the basic DTC, a reference flux vector calculator (RFVC) is used to determine the reference stator flux linkage vector. The reference flux vector is produced according to the amplitude of the reference and estimated stator flux linkages, the position of the estimated stator flux linkage, the amplitude of the reference and estimated torques and the estimated rotor speed. Then the voltage vectors applied on the machine is calculated to compensate the flux and torque errors exactly, so the flux and torque are controlled in the deadbeat fashion. A speed estimation method is also introduced in this paper, in which the rotor flux linkage is calculated from the stator flux linkage and the stator current. Then the rotor speed is calculated from the rotor flux linkage. Simulation results show that the flux and torque ripples are greatly reduced when compared with those of the basic DTC. With the new scheme, the quick dynamic torque response of the basic DTC is still retained. Fixed switching frequency at different operating conditions becomes possible by means of space vector modulation.","PeriodicalId":375971,"journal":{"name":"2009 IEEE 6th International Power Electronics and Motion Control Conference","volume":"23 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-05-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131446555","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}
