Complete PSR and stability analyses are presented. The regulator is implemented in a 90nm CMOS technology and achieves a PSR better than -60dB from 0 to 30MHz with only a 47nF external output capacitor.

Fault-tolerant electrical machines and power converters help achieving this goal but component overrating and system complexity have to be minimised for favourable system designs. This paper will assess several segmentation strategies of fault-tolerant permanent magnet machines on the example of an aerospace actuation system and examine the impacts on system weight and complexity. Considerable detail will be presented on the integration of multi 3-phase machine units in a common motor housing alongside with a detailed comparison between axial and circumferential segmentation, which to the knowledge of the authors has not been published before. A helicopter primary flight control actuation application is used to compare segmentation strategies. Initial results suggest that circumferential machine segmentation and a single layer concentrated winding arrangement are most suitable for applications with a high level of required fault tolerance and high peak to rated torque and speed ratio.","PeriodicalId":301487,"journal":{"name":"2013 IEEE ECCE Asia Downunder","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127315510","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 universal method can be used for both three-phase and single-phase APF by omitting the process of coordinate transformation which used in conventional p-q algorithm and ip-iq algorithm.

Further, multiple local maximum power points appear in the power-voltage characteristics under partial shading conditions, finding the global MPP using conventional MPPT is a difficult task. To solve this issue, the authors proposed a PSO technique to solve the problems involved in the MPPT. PSO-based MPPT can be used only one pair of sensors and able to control by a single centralized MPPT. These methods resulting in lower cost, higher overall efficiency and simplicity of its implementation.

On this basis, a new nonlinear current control method for buck converter is presented first, and a novel integrated control strategy constituting average current mode control and the above nonlinear current control method is proposed for BoCBB converter. With this control strategy, the BoCBB converter can work as a simple boost or a simple buck converter as required. That is, when the input voltage is lower than the output voltage, BoCBB works as a boost converter and the average current control method is used, and when the input voltage is higher than the output voltage, BoCBB works as a buck converter and the above nonlinear current control method is used. Compared with the traditional control scheme that the first-stage boost converter and second-stage buck converter are controlled independently, both the switching loss and voltage stress of the BoCBB can be reduced markedly, and the input current can be controlled more effectively not only in boost work mode, but also in buck work mode. Control diagram is given in this paper, and a 1.5kW rated single-phase boost-buck converter prototype controlled with digital signal processor (DSP) TMS28027 is built to verify the theoretical analysis. Experimental results shows that the output voltage can be regulated at a given value which is lower than peak line voltage, the input current can also be controlled into a sinusoidal waveform, and unit power factor is achieved meanwhile.","PeriodicalId":301487,"journal":{"name":"2013 IEEE ECCE Asia Downunder","volume":"30 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125521580","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 100kW PCSs are cooled only by natural convection. These are the world first PCSs eliminating the cooling fans, in this capacity range, realized by two key factors, loss reduction and sophisticated cooling design. This technology greatly reduces the maintenance works during the PV PCS life cycle and thus contributes efficient operation of PV plants.
