  • Publication number: 20210075340
    Abstract: [Problem] An object is to provide an inverter circuit that can improve the efficiency and stabilize the operation, the inverter circuit executes normal control when the output voltage rises, even when the output frequency is low, and the inverter circuit divides the normal control and regenerative control operations so that the regenerative control is executed when the output voltage drops. [Solution] When the error value is greater than or equal to the first threshold value, the control unit of the inverter circuit executes a normal control of the capacitive load, by operating the primary side switch with the secondary side switch turned off, and on the other hand, when the error value is less than the first threshold value, the control unit executes a regenerative control to the direct current power supply, by operating the secondary side switch with the primary side switch turned off.

  • Patent number: 10158790
    Abstract: An image memory is reduced in an image processing apparatus that generates a background image from which the influence of rain or the like is removed. In the image processing apparatus, a selection unit selects two image signals having a shorter distance in a color space from among an input image signal input during a focused processing cycle among processing cycles executed for respective time-series frames each constituted by the input image signal, an immediately preceding output image signal which is an output image signal generated during a processing cycle immediately preceding the focused processing cycle, and an already output image signal which is an image signal based on the output image signal generated during a processing cycle preceding the focused processing cycle by two cycles. An output image signal generation unit generates the output image signal by mixing the two selected image signals on the basis of a predetermined mixing ratio.
