  • Patent number: 9755544
    Abstract: A power conversion device (1) of the present invention includes a power module (4) for converting direct current electricity to alternating current electricity, first and second power supply buses (5, 6) connecting input terminals (12, 13) and the power module (4), and a metal casing (7) for housing the first and second power supply buses (5, 6) and the power module (4). The capacitive coupling between the first power supply bus (5) and the metal casing (7) and the capacitive coupling between the second power supply bus (6) and the metal casing (7) are substantially matched. Thus, radiation noise is reduced by reducing the propagation of switching noise to the metal casing.

  • Patent number: 9722377
    Abstract: Disclosed is a pluggable power supply device. When a pluggable plug is to be in combination with a power supply seat, an insertion portion is first inserted in an accommodation portion of the power supply seat, allowing a second engagement portion to be engaged with a first engagement portion, and causing the gripping device on the power supply seat to be translated horizontally; a sliding block is then moved horizontally to a separation position and drive a first gripping portion on one side of thereof, allowing a second gripping portion to enter the accommodation portion. Thereafter, an elastic element drives the sliding block to translate horizontally to a gripping position, thereby moving the first gripping portion to be engaged with the second gripping portion. When the pluggable plug is to be removed, it can be taken out only by moving the sliding block horizontally.

  • Patent number: 9722425
    Abstract: In operating an inverter including input connectors, (i) to which strings of photovoltaic cells are connected, (ii) each of which is connected via a DC/DC converter to a common DC voltage link, and (iii) which are bridgeable, the partial powers flowing through the individual DC/DC converters are determined, and for some time at least two DC/DC converters are either operated with the aim of balancing the partial currents flowing through them or connected through. During this operation or connecting through, the partial powers flowing through the at least two DC/DC converters are compared with each other, and if a difference between the partial powers exceeds a threshold value, the DC/DC converters are subsequently operated in a way adjusted to the fact that they connect different strings to the DC voltage link.
