A variety of modes of circuit operation with the voltage and current equations during phase-shift power control under the operating conditions of ZVS and NON-ZVS are analyzed as a first step and the output voltage and current waveforms are obtained by MATLAB program. These waveforms will be analyzed by Fourier analysis which can lead further to the calculation of ac output power Po, dc input power Pd , and hence the conversion efficiency Tj of the half-bridge inverter. The analysis results shows that the control ranges of ac output power Po and dc input power Pd are limited by the occurrence of NON-ZVS operating condition, which changes according to the switching frequency fs .","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"65 6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115883736","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 radially-laminated version of the rotor is described then a machine is developed using the theory. The algorithm is implemented and a design for a 7.5 kW machine is developed to illustrate the sizing required. The machine is of a 2/6 pole arrangement. The paper illustrates that the stator should be specially manufactured because the slots need to be able to cope with a much higher electric loading than an equivalent induction machine. The paper also shows that there is still much work to be done in terms of being able to design and specify this type of novel machine.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132836118","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 effect of the magnetic stimulation depends on the geometry and orientation of the induced electric field, as well as on the current pulse waveform delivered by the stimulator (coil). These factors are very important to define the equipment requirements and characteristics, namely the topology of the power supply and the size and geometry of the coil. The proposed solution is able to generate current pulses with variable amplitude and duration, according to a user- defined input. The main characteristics and the working principle, including the strategy of control, are described. In order to design, to analyse and to verify the performance of the developed power supply, both simulation and experimental results are presented. The proposed solution is based on a topology that uses elements to store and transfer energy from the power source to the load. With the proposed topology, an adequate control strategy and right set of the power circuit parameters it is possible to obtain either unipolar waves or bipolar waves.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127579857","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 case, the VCO (voltage controlled oscillator) is used as A/D signal converter because it has superior response and is low cost. However, prior attempts to improve the transient response have been inconclusive because this model depends on the steady-state analysis. This paper presents a new model control method of switching dc-dc converter to improve the dynamic characteristics. Furthermore, the relationship between the parameters of control circuit and the dynamic characteristics is discussed. As a result, it is seen that the dc-dc converter with a new model control has a superior transient response compared with that of the conventional control. Especially, the overshoot of the reactor current is suppressed to within 34% and this result is approximately 30% smaller than that of the conventional \"static model reference\" control.","PeriodicalId":166704,"journal":{"name":"2007 7th International Conference on Power Electronics and Drive Systems","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133248770","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}
