  • Patent number: 11757370
    Abstract: An energy storage MMC topology is proposed to avoid the microcirculation of battery. The topology consists of six bridge arms in three stages and can be connected to DC system and AC system. Each bridge arm is composed of one bridge arm inductance and N energy storage sub-modules with the same structure in series. The energy storage sub-modules include a half-bridge power module, a battery energy storage module and a group of anti-parallel thyristors. The group of anti-parallel thyristors is connected in series over the DC cable between the battery energy storage module and a capacitor of the half-bridge power module. The switching control is performed on the battery in the energy storage MMC according to the systematic operating mode.

  • Publication number: 20230038475
    Abstract: A telescopic device (100) and a carrying robot (1000). The telescopic device (100) comprises: a loading base plate (10), telescopic arm assemblies (20), and a driving mechanism (30). The telescopic arm assembly (20) comprises at least two which are provided opposite to each other in a width direction of the loading base plate (10); each telescopic arm assembly (20) comprises a fixed arm (21) and a first sliding arm (22), the fixed arm (21) is mounted at the loading base plate (10), and the first sliding arm (22) is slidably provided at the inner side of the fixed arm (21). The driving mechanism (30) is used for driving the first sliding arm (22) to slide with respect to the fixed arm (21) along a length direction of the loading base plate (10). Because the telescopic device can achieve bi-directional extension and retraction, thereby improving carrying efficiency of the carrying robot.
