Finite element simulations show that most of the increased voltage drop at saturation occurs at the end of the channel and in the JFET region close to the channel, which is the region where the current spreads out from the channel. A simplified model is proposed to simply describe the mechanism of current saturation of power SiC MOSFET using a nonlinear voltage source at the end of the channel. The model is validated both statically and under resistive and inductive switching conditions for SiC MOSFET.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"86 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125386788","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}

This disturbance deteriorates the dynamic current-tracking capability and power quality. A unified scalar model is developed to analyze the phenomenon. Based on this model, an improved control scheme with a pre-compensator is proposed to solve the problem. The pre-compensator reshapes the current commands so that the transient disturbance signal is eliminated while the desired response is unaffected. Experimental results of the proposed strategy are compared with the conventional solution to substantiate enhanced dynamic performance.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126782636","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}

To realise the 1 MHz switching capability of the gate driver for SiC MOSFET, the half-bridge topology is used in conjunction with Digital Isolators. The design of the gate drivers takes into consideration the capability of driving SiC MOSFET at 1 MHz switching with less driving power loss and propagation delay. The proposed gate driver is designed and experimentally validated to drive SiC MOSFET at 1 MHz in the 1 kW boost converter. Satisfactory operation of the SiC gate drivers without significant self-heating and with less propagation delay at 1 MHz demonstrates their suitability for high-frequency, high-power applications.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115253009","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, this conventional droop method may cause frequency and voltage deviation, which affects the accuracy of power supply. This paper proposes a novel secondary control strategy to compensate this deviation. This strategy mimics the Master-Slave control but requires no communication lines among the parallel inverters. The master inverter adopts conventional droop method (using power to control frequency and voltage amplitude) and is controlled as a voltage source while the slave inverters adopt reversed droop method (using frequency and voltage amplitude to control power) and are controlled as current sources. The droop characteristic bias of slave inverters is designed online based on the estimation of load power demand. Through this method, frequency and voltage deviation can be eliminated and power sharing can be realized among all the slave inverters. Simulation and experimental results are provided to prove the effectiveness of the proposed control strategy.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116830948","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 impact of ambient temperature, initial conditions of the device prior to avalanche breakdown and the avalanche duration is explored for the different technologies. Two types of tests were conducted namely (i) constant avalanche duration with different peak avalanche currents and (ii) constant peak avalanche current with different avalanche durations. SiC MOSFETs are shown to be the most rugged technology followed by the silicon IGBT and the silicon MOSFET. The material properties of SiC suppress the triggering of the parasitic BJT that causes thermal runaway during avalanche.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129819659","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}

Coupled inductors inside the interleaved boost PFC converter sub-circuit are designed to operate in discontinuous-conduction mode (DCM) for achieving input-current shaping, and the half-bridge-type series-resonant converter cascaded with a full-bridge rectifier is designed for obtaining zero-voltage switching (ZVS) on two power switches to reduce their switching losses. Analysis of operational modes and design equations for the presented LED driver are described and included. In addition, the proposed driver features high power factor, low total-harmonic distortion (THD) of input current and soft-switching. Finally, a prototype 165W-rated LED driver is developed and tested with a utility-line input voltage of 110V. Satisfactory outcomes from experimental results demonstrate the feasibility of the proposed circuit.","PeriodicalId":160988,"journal":{"name":"2015 9th International Conference on Power Electronics and ECCE Asia (ICPE-ECCE Asia)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128324201","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}
