Patent number: 11342847Abstract: A magnetically coupled reactor and a DC/DC converter are provided between a DC power supply and an inverter. A first smoothing capacitor is provided between the DC power supply and the coupled reactor. A second smoothing capacitor is provided between the DC/DC converter and the inverter. A controller is provided in order to control switching operations of the inverter and the DC/DC converter. The controller causes semiconductor switching elements composing upper and lower arms of the DC/DC converter to perform complementary operations so as to be alternately turned on/off, and causes left and right legs to operate with their switching phases shifted from each other, thereby electric charges stored in both smoothing capacitors are discharged by energy loss in the coupled reactor and the DC/DC converter.Type: GrantFiled: February 25, 2019Date of Patent: May 24, 2022Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Satoshi Murakami, Hiroyasu Iwabuki, Yoshihiro Takeshima

Patent number: 11310457Abstract: The present invention provides a method for manufacturing a highly reliable display device at a low cost with high yield. According to the present invention, a step due to an opening in a contact is covered with an insulating layer to reduce the step, and is processed into a gentle shape. A wiring or the like is formed to be in contact with the insulating layer and thus the coverage of the wiring or the like is enhanced. In addition, deterioration of a light-emitting element due to contaminants such as water can be prevented by sealing a layer including an organic material that has water permeability in a display device with a sealing material. Since the sealing material is formed in a portion of a driver circuit region in the display device, the frame margin of the display device can be narrowed.Type: GrantFiled: October 25, 2019Date of Patent: April 19, 2022Assignee: SEMICONDUCTOR ENERGY LABORATORY CO., LTD.Inventors: Shunpei Yamazaki, Satoshi Murakami, Motomu Kurata, Hiroyuki Hata, Mitsuhiro Ichijo, Takashi Ohtsuki, Aya Anzai, Masayuki Sakakura
