  • Patent number: 12074522
    Abstract: For connected-in-parallel N DC-DC converters (1 to N, where N is 3 or more), a first converter group on which PWM switching is performed with a first carrier, and a second converter group on which PWM switching is performed with a second carrier having a phase different from that of the first carrier, are provided. One or more of the DC-DC converters (1 to N) are assigned to each converter group. A plurality of drive modes in which the number of the DC-DC converters that are driven and the converter groups are set, are provided. The drive modes are switched through comparison between a preset threshold value and a total output of the N DC-DC converters (1 to N), and a ratio between total outputs in the first and second converter groups is set to fall within a predetermined range.

  • Patent number: 11321933
    Abstract: An information processing apparatus includes a camera acquiring an image, a memory storing a feature value of an image associated with a location, and a processor. When a current location of the apparatus is not stored in the memory, the processor extracts a first area from an acquired image, acquires a first feature value of the first area, and when a feature value that is substantially identical with the first feature value is stored in the memory, determines the current location using a location stored in the memory in association with the feature value. When the current location is stored in the memory, the processor extracts a second area from an acquired image, acquires a second feature value of the second area, determines a location corresponding to the second area using the current location, and stores in the memory the determined location in association with the second feature value.
