This type of machine can be very effective in the smooth torque and levitation force production.

Moreover, SRMs can drive in high speed region and high temperature condition. These advantages are suited for the automobile auxiliary motors. However, in SRMs driven by voltage single pulse drive, it is difficult to achieve the demanded performances such as torque and efficiency because the output current is not controlled. Especially, the output current is strongly decreased by the back electromotive force in the high speed condition and low voltage source for automotive auxiliary motors. The output current depends on excitation angles, number of turns and motor structure. Therefore, these parameters should be optimized to achieve high motor performances in motor design. However, the method by using FEA requires enormous calculation time and effort. In this research, a novel design method which simply optimizes these parameters by using mathematical formulas is proposed.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"90 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":"115232337","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 the system, a five-leg inverter is proposed; two legs are for the auxiliary motor, three are needed for the main traction motor. Both motors are three phase open-end motors. So the four-switch three phase(FSTP) control scheme for the auxiliary motor is utilized and the two motors could be decoupled controlled under the FSTP scheme. At the same time, the main traction motor and the auxiliary motor together with the inverter are used to construct the charger circuit. So the onboard or off board standalone charger is eliminated. The dual AC motors are used as two inductors, the already available inverter of the two motors are used as an AC/DC converter. The integration of the motor and function of the motor controller/battery charger minimize costs, weight and overall size. The charger is bidirectional, allowing the charging and vehicle to grid(V2G) operation modes.

The 50 kW prototype is developed to validate the proposed notion.

Such characteristics are suited for photovoltaic (PV) or battery application, likes energy storage system (ESS) or electric vehicle (EV). In this paper, the current-fed two-inductor bi-directional DC/DC converter (CF-TIBDC) is proposed. The proposed converter overcomes drawbacks of the conventional CF-TIBC, which are only one way power flow and voltage spike when the switches are turned off. By using the resonant components, the voltage spike problem is solved, and all switches in the CF-TIBDC meet the zero voltage switching (ZVS) condition. Likewise, the zero current switching (ZCS) condition is achieved through the switches on the low voltage stage. A wide range of output voltages with soft-switching is achieved by frequency-duty control. As a result, the proposed converter can maintain high efficiency across the entire range. The principles of the operation characteristics are presented with theoretical analysis, and the proposed converter is verified through PSIM simulation and experiment with a 300W laboratory prototype.","PeriodicalId":324610,"journal":{"name":"2015 18th International Conference on Electrical Machines and Systems (ICEMS)","volume":"50 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":"126162358","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}

Due to the existence of the solar parasitic capacitance to ground, transparent conductive oxide (TCO) corrosion occurs in some type of thin-film solar modules. The negative terminal of the thin-film array can be directly connected to the ground in a single PV-inverter to avoid TCO corrosion. However, a large common-mode current is injected when the negative terminals of parallel inverters connect to the ground directly.

The method obtains the constant charging time of EVs by certainty analysis, then seeks for the period of the lowest total loads in the power system and arranges the charging starting time by reverse recursive principle, thus meets customer charging requirements making full use of the valley period. The arrival time of EV users is simulated by Monte Carlo method, and the load condition of distribution transformer under three charging modes, namely the uncoordinated charging, the charging in the minimum load period and the charging in the reverse recursive period, are simulated and analyzed.
