This topology generates a higher number of output voltage levels, increasing the flexibility for selecting an appropriate voltage vector. The mid-point potential is controlled according to the direction of the mid-point current and the sign of the mid-point voltage deviation. The method is adapted to be used with an LCL output filter, where some undesirable characteristics, such as filter resonance, have to be compensated. Further investigation concerning the dependency of the mid-point voltage with the current phase-shift is given. Theoretical analysis is presented and the performance of the proposed method is verified by simulation.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"42 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115093614","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 further improve the power density, the switching frequency is increased to reduce the EMI filter volume. A design for an 18.5 kW/liter, 2.5 MHz rectifier is proposed. By using today's technology, it is calculated that the maximum power density for a forced air-cooled and water-cooled rectifier is 20.8 kW/liter and 24 kW/liter respectively. To achieve 30 kW/liter, improvements must be made in passive component material properties, reducing semiconductor losses and improving the cooling system.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125230121","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}

In the past, FITMOS was developed for use as a 60 V breakdown voltage element. However, the demand for high-output devices for vehicle system applications has been growing in recent years, and a high breakdown voltage element is needed to meet this demand. The authors therefore utilized an efficient design of experiment, the D-optimal design, in an attempt to simultaneously optimize the complexly linked multiple characteristics and factors of FITMOS. As a result, the authors verified conditions for obtaining characteristics for excellent breakdown voltage (BVds = 74.0 V), on-resistance (RonmiddotA = 36.4 mOmegamm2 @ Vg = 15 V, excluding substrate resistance), and threshold voltage (Vth = 3.0 V).","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116934127","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 HJD achieved lower Von and higher reverse blocking voltage than a commercial Schottky barrier diode (SBD) of SiC. Switching charcteristics of the HJD indicated almost zero reverse recovery similar to that of a SBD. A hetero junction tunneling transistor (HETT) was driven by an insulated gate electrode. The width of the heterojunction barrier was controlled by the gate bias to allow tunneling current to flow. The HETT was fabricated with N+ polycrystalline silicon on an N- 4H-SiC epitaxial layer.

This paper proposes a distributed active filter design for harmonics damping within industry facility. In this system, the active filter operates as a harmonic conductance with a droop characteristic. A droop control bewteen the harmonic volt-ampere reactive consumption of the active filter and its harmonic conductance is developed to coordinate the operation among individual active filters, so that each unit can share harmonic filtering workload in proportion to the rated capacity without any communications.

The dc-dc converter converts fuel cell voltage to a 400-V dc bus voltage using a 3-phase 6-leg phase-shift modulated converter to achieve higher than 96% peak efficiency with zero-voltage zero-current switching. The dc-ac inverter then produces 120/240V ac using a CoolMOS based soft-switching inverter to achieve 98% peak efficiency. The inverter output is universal for both standalone and grid-tie modes operation. The standalone load comes out of two sets of LC filter with a neutral line for equal voltage splits. For grid-tie mode, a circuit breaker needs to turn on, and an additional inductor is included for grid current ripple reduction. Test results indicated that peak efficiency of 94% is achieved for the two-stage power conversion PCS. In addition to high efficiency design, this paper also introduces advanced controls including fuel cell current ripple reduction using a current loop in the dc-dc converter and ac output current steady-state error reduction using an admittance compensation technique in the dc-ac inverter.","PeriodicalId":325362,"journal":{"name":"2007 Power Conversion Conference - Nagoya","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-04-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115524178","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}
