  • POWER CONVERSION DEVICE AND CONTROL METHOD
    Publication number: 20240088778
    Abstract: A controller in a power conversion unit increases or decreases, based on a detected voltage value of a first flying capacitor, a value of a gate voltage to be applied to a gate terminal of a target switch to be controlled selectively from first to fourth switches in a first capacitor circuit to cause conduction between a drain terminal and a source terminal of the target switch, or changes a gradient of the gate voltage value. The controller increases or decreases, based on a detected voltage value of the second flying capacitor, a value of a gate voltage to be applied to a gate terminal of a target switch to be controlled selectively from fifth to eighth switches in a second capacitor circuit to cause conduction between a drain terminal and a source terminal of the target switch, or changes a gradient of the gate voltage value.

  • Generation of haploid plants
    Patent number: 11895960
    Abstract: The present invention relates to non-transgenic and transgenic plants, preferably crop plants, comprising a mutation causing an alteration of the amino acid sequence in the CATD domain of the centromere histone H3 (CENH3), preferably within the loop1 or the ?2-helix of the CATD domain, which have the biological activity of a haploid inducer. Further, the present invention provides methods of generating the plants of the present invention and haploid and double haploid plants obtainable by crossing the plants of the present invention with wildtype plants as well as methods of facilitating cytoplasm exchange.
