  • Publication number: 20240429820
    Abstract: A DC-to-DC converter control method and system based on backstepping super-twisting, a device, and a storage medium are disclosed, the method including: constructing a state-space model of a DC-to-DC converter according to Kirchhoff's laws and a topological structure of the DC-to-DC converter; acquiring initial PWM wave control information by using a backstepping control algorithm in an inner current loop of the DC-to-DC converter according to the state-space model; processing the initial PWM wave control information by using a super-twisting sliding mode control algorithm in an outer voltage loop of the DC-to-DC converter based on the state-space model to obtain final PWM wave control information; and regulating an operation state of the DC-to-DC converter with the final PWM wave control information.

  • Patent number: 11815950
    Abstract: A protective case includes a protective case assembly and a stand assembly disposed in the protective case assembly. The protective case assembly includes a bottom cover. A convex ring is arranged at one side of the bottom cover and a gear ring is arranged on the inner circle of the convex ring. A metal dome works with the gear ring to adjust the angle of the lower stand cover. Both the stand assembly and the protective case assembly can be disassembled, separately used, and separately replaced in case of damage. A support strip after being flipped over is positioned and unlocked via a button. The support strip is locked by a positioning buckle when recovery.

  • Patent number: 11796128
    Abstract: A multi-functional magnetic bracket includes a first bracket with a magnet disposed therein to magnetically attach the first bracket to mobile phone; a second bracket movably connected to the first bracket through a connecting arm, the second bracket and a hinging arm being accommodated to inside of the first bracket, and a ring and a tooth slot opened in the second bracket; and a connector disposed in the second bracket and combined with the second bracket to form a multi-platform bracket for mounting the second bracket on different scenarios and platforms. The connector includes a base of which a surface is adhered to the platform, a limiting buckle disposed in the base and of which one end extends to a side of the second bracket, and a spring bead disposed in the base and of which one end extends to inside of the tooth slot.
