Abstract: A power converter for a power system performs power control of a power system by using a first control value derived based on a first stabilization command value for causing a voltage on a first DC bus to be within a first range and a first control command value different from the first stabilization command value. A power converter for a solar cell performs power control of a solar cell by using a second control value derived based on a second stabilization command value for causing a voltage on a second DC bus to be within a second range and a second control command value different from the second stabilization command value. The first range is narrower than the second range.

Abstract: An inverter device, including: a booster circuit that includes a switch element and a booster coil, the booster circuit boosting a voltage of direct-current power by the switch element being driven using a first on-off signal; an inverter circuit that includes switch elements, the inverter circuit converting the direct-current power, which is outputted from the booster circuit, into alternating-current power by the switch elements being driven using a second on-off signal; a coil for filter through which the alternating-current power passes; and a control unit configured to drive (i) the switch element using the first on-off signal for which a duty cycle is changed according to a first frequency, and (ii) the switch elements using the second on-off signal generated based on a carrier wave having a second frequency higher than a first frequency and a modulation wave having a frequency which synchronizes to a frequency of a power grid.

Abstract: An inverter device converts a DC power into a three-phase AC power and superimposes the AC power on a power grid. A method for controlling the inverter device includes: obtaining, when the three-phase AC power is formed to contain a reactive power having a same amount in each of phases of the three-phase AC power, frequencies of respective phases of the power grid as present frequencies; controlling the reactive power to be contained in each of the phases to have a same amount such that the frequencies further increase when the present frequencies are higher than previous frequencies which have been obtained before the present frequencies are obtained, and such that the frequencies further decrease when the present frequencies are lower than the previous frequencies; and detecting a power outage state of the power grid based on the present frequencies of the respective phases and the previous frequencies.

Abstract: A power storage unit includes a battery module housed in a battery case. The battery module has, as components, a plurality of battery cells stacked and arranged in a direction (direction Y) crossing a transverse direction. Reinforcing members arranged at a predetermined spacing are provided between the battery cells. The power storage unit of this structure can prevent damage to the power storage unit disposed between seats adjacent to each other in the transverse direction, when frame members provided in the seats are moved in the transverse direction in the event of a crash of a moving conveyance.

Abstract: There is provided a sun visor holder wherein efficiency with which the sun visor holder is mounted on a body panel is greatly improved. A sun visor holder includes holding pieces engaging with an interior material, and also includes engaging claws engaging with and nipping a body panel, and a flange portion. The sun visor holder can be mounted at the body panel in a state of being temporarily fastened to the interior material, and can also be mounted by simply being inserted in mounting holes. Therefore, the efficiency with which the sun visor holder is mounted on the body panel is greatly improved.

Abstract: A room lamp fixing structure having a temporary fixing means provided for a room lamp and a ceiling trim and a permanent fixing means provided for the room lamp and a ceiling framework of a car body. This construction includes a ceiling trim having a recess for accommodating the room lamp, the recess having its side surface inclined so as to become gradually narrow from the opening portion to the bottom portion, and a room lamp having in its side surface a guide projection for positioning the room lamp and the ceiling trim by abutting against the slant side surface of the recess during the permanent fixing. This structure allows the guide projection to abut against the slant side surface, and thereby the room lamp and the ceiling trim are positioned.

Abstract: An impact energy absorbing structure includes a front pillar (30) including flange joint portions (44, 45) where flanges respectively of an outer panel (38) and an inner panel (40) are overlapped and joined, a pillar garnish (32) disposed with a space (d) from the front pillar, an energy absorber (34) disposed in the space, and a plurality of abutting ribs (36). The abutting rib is formed so as to bump against the flange joint portion (44) when the pillar garnish deforms outwardly.
