Publication number: 20150115286Abstract: An SiC semiconductor device has a p type region including a low concentration region and a high concentration region filled in a trench formed in a cell region. A p type column is provided by the low concentration region, and a p+ type deep layer is provided by the high concentration region. Thus, since a SJ structure can be made by the p type column and the n type column provided by the n type drift layer, an on-state resistance can be reduced. As a drain potential can be blocked by the p+ type deep layer, at turnoff, an electric field applied to the gate insulation film can be alleviated and thus breakage of the gate insulation film can be restricted. Therefore, the SiC semiconductor device can realize the reduction of the on-state resistance and the restriction of breakage of the gate insulation film.Type: ApplicationFiled: June 6, 2013Publication date: April 30, 2015Applicant: Denso CorporationInventors: Yuichi Takeuchi, Naohiro Suzuki, Masahiro Sugimoto, Hidefumi Takaya, Akitaka Soeno, Jun Morimoto, Narumasa Soejima, Yukihiko Watanabe

Patent number: 8435688Abstract: A fuel cell two-wheel vehicle is provided with: a fuel cell, fuel tanks, a supercharger, a pipe line, an in-wheel motor, and a motor driver. The fuel cell generates electric power using hydrogen and air as reaction sources. The fuel tanks supply hydrogen to the fuel cell through a hydrogen supply path. The supercharger supplies air from the outside air to the fuel cell. Through the pipe line, an exhaust from the fuel cell is discharged to the outside. The in-wheel motor serves as a driving source of the fuel cell two-wheel vehicle, and the motor driver drives the in-wheel motor. In an air system, a route and an outlet of the pipe line are arranged to be directed toward the motor driver. Thus, a heat sink is exposed to the discharged air having passed through the fuel cell, and thereby the motor driver is cooled.Type: GrantFiled: November 29, 2006Date of Patent: May 7, 2013Assignee: Honda Motor Co., Ltd.Inventors: Masahiro Shimizu, Hiroyuki Kikuchi, Junya Watanabe, Tomoyuki Sahata, Jun Morimoto
