Patent number: 9686890Abstract: A structure for efficiently transferring heat generated from an electronic part or the like to a heat dissipation member is provided. A bus bar is used for a wiring pattern in an electronic device (60), such as a power line (2), a GND line (6) and the like. A heat transfer member (25) is held between a first bus bar that is a power line (2) connected to an electronic part and a second bus bar that is a GND line (6) connected to a heat dissipation member (7) to configure a heat dissipation structure in which heat generated from the electronic part is transferred through the power line (2), the heat transfer member (25) and the GND line (6) to the heat dissipation member (7).Type: GrantFiled: October 4, 2013Date of Patent: June 20, 2017Assignee: Mitsubishi Electric CorporationInventors: Shingo Akamatsu, Mitsuo Sone

Patent number: 9174542Abstract: The invention has an object of providing a power supply device for vehicle of high efficiency while keeping longer service life of a capacitor. By supplying an electric power of a capacitor to various electronic devices for a first predetermined time period after a vehicle engine has been stopped and discharging an electric power of the capacitor to a battery for a second predetermined time period after the first predetermined time period has ended, the voltage of the capacitor is reduced. By forcing the electric power of the capacitor to discharge at a forced discharge circuit until the voltage of the capacitor is substantially equal to a predetermined voltage after the second predetermined time period has ended, the time period during which the capacitor is held at a high voltage is made shorter. Longer service life of the capacitor and higher efficiency of the power supply device can be achieved.Type: GrantFiled: May 23, 2011Date of Patent: November 3, 2015Assignee: Mitsubishi Electric CorporationInventors: Mitsuo Sone, Nobuhiro Kihara, Fumito Uemura

Patent number: 9148968Abstract: When a housing of a waterproof main terminal is fixed onto the outside surface of a case with a screw, a through hole is sealed with a seal surface of a packing pressed onto the outside surface of the case. Furthermore, the elastic force of the packing placed so as to be in tight contact with the whole circumference of the terminal ensures high waterproofing performance between the terminal and the housing, so the one packing can perform waterproofing both between the case and the housing and between the terminal and the housing.Type: GrantFiled: October 1, 2013Date of Patent: September 29, 2015Assignee: Mitsubishi Electric CorporationInventors: Mitsuo Sone, Hisakazu Yamane

Patent number: 8829860Abstract: A power storage apparatus provided with a capacitor module and a power storage control circuit is connected between a generator and an electrical load. The capacitor module includes a plurality of capacitors and a plurality of switching devices which are connected in series with the capacitors, respectively, the capacitors and the switching devices together constituting a plurality of series circuits which are connected parallel to each other. When starting up the generator, the power storage control circuit controls only the specified switching device to become ON in order to quickly charge the capacitor which is connected in series with the switching device so that a voltage of the capacitor module is increased and a power source for starting up the generator is produced as high speed.Type: GrantFiled: October 13, 2011Date of Patent: September 9, 2014Assignee: Mitsubishi Electric CorporationInventors: Mitsuo Sone, Nobuhiro Kihara

Patent number: 8670258Abstract: A power supply device includes a failure determination means that detects, based on a current detected by a current detector, a failure of the switching elements of each of the chopper sections, and the failure determination means obtains values of the current detected by the current detector at the timing of falling edges of control signals to the switching elements of each of the chopper sections, determines the failure when the obtained current values differ from each other, and transmits a failure signal to a generation control means. When receiving the failure signal, the generation control means limits an output current from a generator in a way such that the withstanding current of a non-failed chopper section out of the chopper sections of the phases is not exceeded.Type: GrantFiled: January 12, 2012Date of Patent: March 11, 2014Assignee: Mitsubishi Electric CorporationInventors: Toru Daigo, Nobuhiro Kihara, Naoki Itoi, Mitsuo Sone
