However, it is challenging to achieve fully sliding mode under a low sampling frequency, especially for high speed and heavy load applications. In order to overcome this problem, a multilayer DSMO is proposed to estimate the rotor position from the extended back electromagnetic force (EMF). To guarantee a fast response to speed and torque variations, the width of the boundary layer of the DSMO is designed to be adaptive to speed and torque variations. A parameter adaption scheme based on control law and sliding-mode dynamics is proposed for selecting the width of the boundary layer and the observer gain. The proposed multilayer DSMO is validated by simulations and experimental results on a 150 kW IPMSM drive system used for hybrid electric vehicles.","PeriodicalId":6401,"journal":{"name":"2012 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"11 1","pages":"1788-1795"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85911756","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 distribution of currents and power extraction improvement have been derived and verified experimentally and design guidelines to meet desired power loss level requirements have been developed. The experimental equalizing module was designed for 185W PV panels and was found to boost the maximum available power by about 50% when interfaced with two serially connected PV panels under insolation ratios between 20% and 100%.

The magnetic design of the receiver/secondary and transmitter/primary pads is the most critical part of an IPT system design. This paper presents the performance of a Bipolar Pad (BPP) receiver in a lumped IPT system for EV charging systems and compares it against the performance of a recently proposed receiver design, Double-D Quadrature Pad (DDQP). A 3D finite element modeling tool, which has shown good agreement between measured and simulated results in the past, is used to simulate all the models presented in this paper. The prototype models are also built and tested to verify the simulated results. Although it has been shown that the polarized single sided flux pad design, Double-D Pad (DDP), has much better performance than the non-polarized single sided flux pad design, Circular Pad (CP), still the ability of a receiver pickup to interoperate with both types of transmitters is considered to be highly desirable. In this paper the performance of a BPP receiver is compared against the performance of a DDQP receiver when used with either a DDP transmitter or a CP transmitter. The results show that the BPP receiver approximately matches the output levels provided by a DDQP receiver while using less amount of copper. Finally, the possibility of improving the ability of both the BPP and DDQP receivers to interoperate with both DDP and CP transmitters by changing the receiver ferrite structure is investigated. The results however indicate that for both the BPP and the DDQP receiver designs, the traditional ferrite structure exhibits best material usage efficiency amongst the design possibilities considered in this paper.","PeriodicalId":6401,"journal":{"name":"2012 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"32 1","pages":"283-290"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82273914","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}

However, at ultra high frequency the resolution is too low to control the converter. A high resolution digital phase-shift modulation scheme to improve the resolution of the phase-shift angle by a factor around 50 is proposed for a 500kHz dual active bridge type converter. The implementation issues such as the micro-edge positioning and deadtime generation are discussed. The experimental measurement of the gate signal time change with different input angles verifies the high resolution of the phase-shift angle with the proposed scheme. When the maximum phase-shift angle is 30°, a resolution of 0.09% is obtained and the closed-loop digital control with presented high resolution modulation scheme is validated in a 500kHz prototype.","PeriodicalId":6401,"journal":{"name":"2012 IEEE Energy Conversion Congress and Exposition (ECCE)","volume":"19 1","pages":"1684-1691"},"PeriodicalIF":0.0,"publicationDate":"2012-11-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81386221","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 dc circuit breaker is a solid-state breaker which consists of many semiconductor devices in series with maintaining equal voltage balancing, making it possible to apply to high voltage applications. Moreover, the surge voltage across the circuit breaker is reduced by employing a freewheeling diode. In a system rated at 300 MW in power and 250 kV in dc voltage, conduction loss of the proposed circuit breaker consisting of 4.5 kV devices is estimated at 0.045% of the rated power, which is enough small comparing to the VSCs' power loss.
