A very simple mapping is used to achieve the SVPWM for any n-level inverter. In addition a dead-band hysteresis is introduced in the SVPWM algorithm to avoid the output voltage level jumping. The simulation results show the effectiveness of the proposed method.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121856349","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 haptic information is effective for medical and industry. In conventional research of haptics, low degrees of freedom system is often used. However, to transmit human-like haptic information, human type robot should be used. In this research, a finger type robot with 10 degrees of freedom is used as slave system to transmit haptic information. This robot is chain driven robot. This structure can transmit better haptic sense than serial link robot because the inertia of each joint is low and gear ratio of motor is low. When human grips something by hand robot, it is thought that grip force can be simplified to one degree of freedom force. Thus, in this research, the hand robot as slave system and one degree freedom linear motors are used as master system for the simplicity of system setup. The system of this research is constructed with different degree of freedom robot. To transmit haptic sense this system, hierarchical bilateral control is proposed. The control method realizes transmission of haptic sensations between systems with the different degree of freedom. By the experiments, viability of proposed method is confirmed.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122391766","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}

An LC output filter is connected between the converter and the load. The four-leg indirect matrix converter is developed to deliver power to the unbalanced/nonlinear three-phase loads and it can produce three output voltages independently with one additional leg. The proposed voltage control strategy is based on prediction calculation to select the switching states of the converter. By using a predictive cost function, the optimal switching state to be applied to the next sampling time is selected. This is done in order to obtain unity displacement power factor in the input side and a positive dc-link voltage at any time, while maintaining a good tracking of the load voltages to their respective references. The feasibility of the proposed strategy is verified by simulation results.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115046477","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}

All the available switching states (32 in total) are included in the optimization process. Impact of the x-y currents' weighting factor (Wxy) and stator fundamental frequency on the average values in both the primary and the secondary plane and on the phase current ripple are investigated using simulation.

The output voltage can be then adjusted within the two resulting voltage ranges by either varying the switching frequency of the converter or utilizing a post regulator. In the last option, the three-level converter works as an electronic transformer with variable turns ratio. Therefore, the converter can be designed to operate with a narrow operation condition maintaining high efficiency despite of wide-voltage range variations. A hybrid gate driver which simplifies the implementation of the proposed modulation method is also presented. The novel modulation method is analysed and verified on a 20kW, LLC three-level resonant prototype operating at 110 kHz.","PeriodicalId":293242,"journal":{"name":"2012 15th International Power Electronics and Motion Control Conference (EPE/PEMC)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2012-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125511570","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}
