Patent number: 8648574Abstract: A power generator has a battery and an alternator driven by an engine. The battery assists a power energy of the alternator. An inverter circuit is connected to an output of a rectifying circuit. A DC/DC converter boosts a voltage of the battery and inputs the boosted voltage into a constant power regulator. The constant power regulator boosts an input voltage and secures a certain power. An output voltage of the rectifying circuit is monitored by a monitoring means and an output voltage of the battery is monitored by a monitoring means. When the output voltage of the rectifying circuit is equal to or less than a rated voltage, an auxiliary power value corresponding to the remaining amount of the battery is set as a power target value of the constant power regulator.Type: GrantFiled: April 28, 2011Date of Patent: February 11, 2014Assignee: Honda Motor Co., Ltd.Inventors: Masanori Ueno, Makoto Ogawa

Patent number: 8598723Abstract: A power generator starts an engine by overcoming an inrush current occurs. A calculator (21) retrieves an outputtable current of a generator according to an engine speed. A calculator (23) calculates the lacking amount of the outputtable current relative to a load current. When the remaining battery level is sufficient, a DC/DC converter controller (24) supplies a current corresponding to the lacking amount from the battery (4) to a DC part (52). If the battery (4) starts supplying a power, FETs (Qa to Qf) of a rectifying part (51) are powered off and an output of the power generator (3) is stopped. When an engine frequency stability deciding part (27) decides the engine frequency is stable the rectifying part (51) restarts the output of the generator (3) and the current supply from the battery (4) to the DC part (52) is stopped.Type: GrantFiled: April 28, 2011Date of Patent: December 3, 2013Assignee: Honda Motor Co., Ltd.Inventors: Takashi Hashizume, Masanori Ueno, Makoto Ogawa

Publication number: 20120079446Abstract: A semiconductor module made from a compound semiconductor or diamond and loaded with high performance power semiconductor devices can be obtained at low cost. In a semiconductor module, four (semiconductor chips) of same specifications are arranged in array, two longitudinally and two transversally, on a single lead frame. Achieving a high yield of manufacturing diode chips and reducing the unuseful area of diode chips need to be satisfied at the same time to obtain such a semiconductor module at low cost. The use of an index, which is the product of the yield YDie of manufacturing chips and the active region area ratio RA is effective for determining them. Thus, semiconductor modules can be obtained at a high yield by selecting a chip size that makes the index close to a peak value depending on the crystal defect density of a wafer to be used.Type: ApplicationFiled: September 21, 2011Publication date: March 29, 2012Inventors: Hiromichi KUMAKURA, Hiroyuki Ogino, Kenji Fujimoto, Masanori Ueno

Publication number: 20110260452Abstract: Usability is improved and noise and fuel consumption are lowered by preventing stopping of a generator output. A hybrid power generator 1 includes a battery 4, an alternator 3, a rectifier unit 51, a DC-DC converter 9 stepping up an output of the battery 4, and an inverter unit 53 converting outputs of the rectifier unit 51 and the DC-DC converter 9 to AC and outputting the AC as a generator output. At a time when a load output reaches an upper limit of an allowable power range of the DC-DC converter 9, the engine 2 is started and power supplying from the battery 4 is switched to power generation by the alternator 3. A generated power restricting unit 27 suppresses the output of the inverter unit 53 during the starting of the engine so that the generator outputs allowable power range of the DC-DC converter 9.Type: ApplicationFiled: April 6, 2011Publication date: October 27, 2011Applicant: HONDA MOTOR CO., LTDInventors: Makoto OGAWA, Masanori UENO

Publication number: 20110260546Abstract: Suppresses noise due to high engine speed and improves emission and fuel consumption of a hybrid generator. A difference computing unit 29 computes a first difference between an alternator output and a load output. A difference computing unit 31 computes a second difference between a battery output and the load output. When the battery output is greater than a battery output stopping threshold, the alternator output is fixed and the first difference is compensated for by the battery output. When the battery output is less than the battery output stopping threshold, the engine speed is increased to compensate for the second difference by the output of the alternator 3. To compensate for the second difference, a target engine speed is determined using a relationship of the second difference and the target engine speed. The engine speed is converged at the target engine speed.Type: ApplicationFiled: April 11, 2011Publication date: October 27, 2011Applicant: HONDA MOTOR CO., LTD.Inventors: Takashi HASHIZUME, Makoto Ogawa, Masanori Ueno
