This model combines control strategy and finite element model (FEM) of motor, which can consider the effects of magnetic saturation and rotor position.

The main objective is to reduce the electromagnetic interference (EMI) by reducing the common-mode noise current being generated from the effect of PWM signal of active filter. For this reason, this common-mode noise current flows through the reference ground and generates the conducted noise emission flowing around the circuit. Thus, this paper suggests the common-mode circuit balanced method by modifying the impedance of common-mode circuit impedance. The result shows that the common-mode currents is cancelled themselves. From the experimental results, both the spectrum of conductive noise before and after improving is compared.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122634133","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 harvester utilizing the Villari effect (inverse-magnetostrictive effect) consists of a coil-wound Terfenol-D rod. To generate more electrical power, a PM (fixed on the part of cap amplifier) and variable-length air-gap are designed in each magnetic circuit, which helps to enlarge Villari effect in Terfenol-D rod in the action of environmental vibration. The magnetic field and its leakage in harvester are analyzed, and principal design parameters of harvester are optimally determined. Then, a prototype is fabricated and tested, and its harvesting effect is calculated. The harvester exhibits high power density, can generate up to 0.022 T/MPa piezomagnetic effect and safely used in up to 20MPa transient impact.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122867777","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 reliability of the charge equalizer can be enhanced because the split capacitors are not required and the soft-switching of power switches can be achieved by the proposed control. In addition, the number of the bridge-rectifiers at the secondary-side of the transformers can be reduced by half, which also cut the cost and conduction loss by half with the proposed rectification. The circuit topology and operation analysis of the proposed charge equalizer are described.

However, exploiting ZVL to minimize losses of SRMs has been challenging due to nonlinear correlations caused by extensive magnetic saturation. In this paper, an optimization method to minimize losses while utilizing ZVL is proposed. The Impact of ZVL was investigated by theoretical calculation using a 12 kW, 3820 rpm SRM. The results showed that the utilization of ZVL reduced losses at all speed and partial load. The loss reduction was large especially at medium speed and partial load. At this operating point, the loss reduction was verified by experiment.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125668989","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}

To transform from task space to joint space, inverse kinematic is used to calculate. However, the system has a time delay and its equations are complication because of nonlinear equation. In this paper, an Adaptive Neuro Fuzzy Inference System (ANFIS) method is used to calculate the inverse kinematics in the easy way. Task space position is transformed to joint space by using ANFIS, therefore it can decrease the complication of the nonlinear equation. Moreover, the force response is transfer between master and slave robot using Jacobian Matrix and negated the gravity force and also the task space position control using forward and ANFIS inverse kinematic. The control system uses disturbance observer (DOB) to estimate sum of action/reaction force of master-slave delta robot instead of the force sensors.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"43 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129729348","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}
