Patent number: 7599754Abstract: After specifications of a power converter are determined, circuit parameter values, a semiconductor device to be used, and an equivalent circuit of the semiconductor device are determined, and parameter values of the equivalent circuit are extracted. Semiconductor device loss is calculated from semiconductor device equivalent circuit parameter data, circuit parasitic parameter data, and circuit basic parameters. Determination as to whether or not the circuit loss optimal value has been achieved is made in consideration of power conversion circuit component parameter data. When the optimal value has not been achieved, the circuit parasitic parameter values are set again so as to create the circuit parasitic parameter data. When the optimal value has been achieved, the semiconductor device loss and the circuit parasitic parameter values at that time are output as design data, and the power converter is designed by use of the optimized semiconductor device loss and circuit parasitic parameter values.Type: GrantFiled: June 4, 2007Date of Patent: October 6, 2009Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Hiromichi Oohashi, Kazuto Takao, Yuusuke Hayashi

Publication number: 20070279957Abstract: In a power integrated circuit, a voltage-type single-phase full-bridge conversion circuit is used as a basic unit. The basic unit includes a level-shift-type gate drive circuit. An integrated single-phase multi-level conversion circuit is formed by connecting basic units in series. An integrated three-phase multi-level conversion circuit is formed by connecting three basic units in parallel or by connecting three sets of serially connected basic units in parallel. Since the output multi-level voltage waveform of the integrated single-phase or three-phase multi-level conversion circuit is low in harmonic content, it can constitute a single-phase or three-phase power converter without use of a passive filter.Type: ApplicationFiled: June 4, 2007Publication date: December 6, 2007Inventors: Hiromichi OOHASHI, Yuusuke HAYASHI, Tatsuto KINJOU
