A simulation shows that switching speed is decreased by the stray capacitance on the inverter output electrode pattern. The design guidelines focusing on reduction of the stray capacitance are proposed. Further, based on the guidelines, a SiC-MOSFET VSI to reduce the stray capacitance is designed using a double-sided PCB with 35 μm-thick standard copper foil. Experiments using SiC- MOSFET VSIs show that the inverter with the redesigned PCB shortens the switching time of the drain-source voltage by 10% for the rise time and by 38% for the fall time compared with an inverter based on our previous design guidelines. Hence, the switching loss is also reduced using the redesigned PCB inverter.","PeriodicalId":230939,"journal":{"name":"2019 IEEE 4th International Future Energy Electronics Conference (IFEEC)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132016987","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 paper presents an electro-thermal coupling model to estimate the temperature in supercapacitor. Firstly, an electro-thermal coupling model is built for the purpose of online temperature observation. Secondly, in order to improve the accuracy of the model for online application, a H infinite filter is designed for the model. The results of experiments show that electro-thermal coupling model achieves good accuracy. The absolute error of temperature is less than 1.4°G. Moreover, after adding the H infinity filter to the electro-thermal coupling model, the accuracy of the model is greatly improved, and the absolute error is less than 0.4°C.

The neutral-point voltage of the T-type inverter may suffer from low-frequency oscillation due to third harmonic current, thus detreating maximum point tracking (MPPT) of series solar panels. This paper proposes a new modulation for the T-type inverter to suppress the neutral-point oscillation even under the condition of unbalanced neutral-point voltage. Thus, the dc-side capacitance of the inverter can be significantly reduced and film capacitors are able to replace electrolytic capacitors to increase the lifetime of the inverter.

In this power flow direction the discontinuous and continuous conduction mode of the bidirectional converter are discussed. For a power flow from the safety extra low voltage respectively battery side the converter works in continuous conduction mode as a boost converter. After introducing the specification of the mobile battery application, the topology and the modulation scheme are presented.

Minimal use of analog circuitry in the architecture not only reduces the power consumption but also makes the design simple to realize. The scheme offers tolerance against variations in process and temperature by comparing the sensed voltage against a reference voltage that is reflective of the amount of variation present. Proposed circuit schematic was designed and simulated using 55nm CMOS technology alongside a switching regulator. The simulated circuit could measure currents up to 600mA with a maximum measurement error of only +/−2.5%.
