The performance of IGBTs under short circuit and clamped inductive load conditions has been studied in detail with the aid of extensive measurements and numerical simulations. An advanced mixed device and circuit simulator is employed to study the internal dynamics of latch-up free punch-through IGBT. It is shown that thermally assisted avalanche breakdown of IGBT under the two stress conditions occurs due to localized high temperature generation in different regions of the device.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"2 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115490638","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 synchronous switch technique is employed to synthesize the SSCs which can fulfill maximum power point tracking, battery charging, discharging and lamp ballasting features. Several typical SSCs are discussed in the paper. One of the proposed SSCs, which is the integration of a buck-boost charger/discharger and a class-D series resonant parallel loaded inverter, is analyzed and designed. Both pulse-width modulation and variable-frequency controls are used to govern the system. The controller is implemented on a single-chip microprocessor. Simulated and experimental results of the proposed system for driving sixteen GE TBX 26 W fluorescent lamps are used to verify the theoretical prediction and feasibility. The proposed system has the merits of lower cost, more compact size and possibly achieving higher reliability over conventional systems.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116937780","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 technique requires coordination of an outer speed loop with an inner current loop. The inner current loop is responsible for shaping the phase currents during the commutation intervals. The outer speed loop is responsible for commanding the magnitude of the phase currents. It is shown that the speed loop must be sufficiently fast that the commanded phase current is able to respond to potential ripple torque during phase commutation; a simple direct adaptive controller satisfies this requirement. The inner current loop must be able to adaptively change the slope of the commanded current in order to avoid poor current regulation through inverter saturation in the face of large back EMFs. The composite control is able to reduce torque ripple to a level which is dictated by phase ripple currents.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116057769","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 address this issue, more attention has recently been given to the reduction of electromagnetic emissions created by power electronics. The proliferation of solid-state inverters brings the cost of semiconductors down, making active filtering an attractive alternative to passive filter topologies. Active filtering may also realize higher efficiency than passive filtering. This paper focuses on an active filter topology that significantly reduces the common mode voltage created by voltage source inverters. The reduction of common mode voltage is achieved by introducing a novel inverter topology and a new hysteresis modulation strategy to control this inverter topology.","PeriodicalId":156715,"journal":{"name":"APEC '98 Thirteenth Annual Applied Power Electronics Conference and Exposition","volume":"179 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1998-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123032950","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}
