Development of SiC MOSFETs allows fast switching commutation. In order to fully utilize their ability in high frequency application, the impact of common source inductance on the switching loss should be explored. This paper proposes a method to experimentally study the influence of common source inductance on switching loss of SiC MOSFET. The switching loss is calculated by measuring the device junction temperature and calibrating thermal resistance from the SiC chip to the heatsink. ZVS soft switch method is used to separate the turn on and turn off losses by comparing the switching loss and substituting the turn off loss. A 1kW/800V output all-SiC boost DC-DC converter is built to accomplish the study.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"51 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115813094","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}

Contrary to previous WPT systems for RPEVs, the proposed U-WPT can also be used for pick-ups fabricated by the SAE J2954 standard for stationary charging. The proposed U-WPT adopts a new coreless power supply rail to increase its operating frequency from the conventional level of 20 kHz to 85 kHz, as specified in the SAE J2954 standard. With the adaptation of U-WPT, EVs in the future will simply be called wireless electric vehicles (WEVs) regardless of whether they use stationary or dynamic charging systems. A detailed comparison between coreless and with-core power supply rails is thoroughly made, with the results verified in simulations and experiments. This comparison shows that, with the same power rating, the proposed coreless power supply rail is superior to the conventional with-core power supply rail due to its low cost, less insulation voltage stress, lack of core loss, and only slight sensitivity to lateral misalignment, mitigating the condition of less induced voltage.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129538208","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 AVFC is fulfilled with two diodes, one integrator, and one subtractor to sense the voltage variation among the current regulators and then to generate an adaptive reference voltage. According to the reference voltage, the output voltage of the boost converter is automatically regulated, so as to keep a minimum voltage on the current regulator and maintain the required LED-string current. A prototype driver implemented with 0.35-μm 2P4M CMOS process validates the proposed technique.

Generally, series-connected insulate gate bipolar transistors (IGBTs) were implemented in solid-state DC breaker to withstand the turn-off transient overvoltage across it. However, the IGBTs are expensive power semiconductor devices that are highly sensitive to transient overvoltage, thus their voltage balancing during the turn-off transition need to be carefully concerned. This paper investigates the voltage unbalancing factors of the series-connected IGBTs in a solid-state DC breakers first. Aiming at synchronizing the voltage overshoot amplitude of the series-connected IGBTs during the circuit breaking, an active gate drive circuit and its corresponding voltage balancing technique are proposed. It is shown in small-scale experiment that if the voltage overshoot deviation between series-connected IGBTs are effectively minimized.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"10 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116373618","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}

Position sensorless control at low speeds of SynRMs is now desired, and several methods have been proposed. This paper proposes a new position sensorless control method of SynRMs at low speeds by estimating a high-frequency extended e.m.f.(EEMF) caused by injecting a high-frequency current, by a disturbance observer on the stator frame. In this method, the frequency of the injecting high-frequency current is set to 200 Hz which is quite lower than a mechanical resonance frequency of the motor, to consider reduction in noise of the motor. The superimposed signal of thus low frequency influences the current control system driving the motor. Therefore, this paper proposes a new method for eliminating the superimposed signal by subtracting a reference value of the high-frequency current from the current fed back to the current controller. Finally, it is experimentally shown that the position sensorless control is capable, at low speeds and under load conditions, using the proposed method.","PeriodicalId":268430,"journal":{"name":"2015 IEEE 2nd International Future Energy Electronics Conference (IFEEC)","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123825823","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}
