  • Publication number: 20250105737
    Abstract: A switch control circuit comprises a comparison branch and a feedback branch. The comparison branch controls the turning off of the second power switch in the power conversion circuit based on the polarity of the voltage difference between the common node and the first voltage. The feedback branch generates a feedback signal based on the polarity of the first signal after the second power switch is turned off and a delay of the first duration and adjusts the first voltage. The first signal can be a voltage difference or the voltage of the common node. If the polarity of the first signal is positive, the first voltage is reduced to make the comparison branch turn off the second power switch earlier. If the polarity of the first signal is negative, the first voltage is increased to make the comparison branch delay the turning off of the second power switch.

  • Publication number: 20250083974
    Abstract: A core-shell gradient ternary precursor and a preparation method and application thereof. The preparation method includes (1) mixing a terephthalic acid solution with alkaline liquor to obtain a terephthalic acid salt solution, adding a nickel source solution for a reaction to obtain a Ni-MOF solution, mixing the Ni-MOF solution with ammonia water, and adjusting a pH value to obtain a base solution; and (2) adding a nickel-cobalt-manganese ternary mixed salt solution, a liquid alkali solution, and an ammonia-water solution simultaneously to the base solution obtained in step (1) for a co-precipitation reaction, and obtaining the core-shell gradient ternary precursor after aging treatment. The Ni-MOF is pre-prepared and used as a core for the co-precipitation reaction, to obtain the core-shell like precursor with a gradient. Carbon in the core of the core-shell gradient ternary precursor reacts with oxygen, thereby reducing a nickel oxidation state on particle surfaces and reducing crack generation.
