  • Publication number: 20180212526
    Abstract: An isolated switching mode power supply and a control method of the isolated switching mode power supply are provided. The isolated switching mode power supply includes a primary side circuit and a secondary side circuit. The primary side circuit includes a controller. The secondary side circuit is coupled to the primary side circuit and includes a winding, a switch, and an SR controller. The winding is coupled to the primary side circuit. The switch is coupled to the winding. The SR controller is coupled to the winding and the switch. The SR controller turns off the switch to trigger the winding to feed back a first message to the primary side circuit. The controller enables the primary side circuit to transfer energy to the secondary side circuit if the controller detects the first message.

  • Publication number: 20170328463
    Abstract: A linear transmission device includes a shaft, a moving member movably provided on the shaft, and a lubrication unit provided at the moving member. The lubrication unit has a lubricant container and a block. The lubricant container has a storage space which communicates with the interior of the moving member via a lubricant dispensing opening. The block is provided in the storage space of the lubricant container and can be displaced by an inertial force generated by movement of the moving member so that, during its displacement, the block squeezes the lubricant in the storage space, thereby driving the lubricant into the interior of the moving member through the lubricant dispensing opening for lubrication.

  • Patent number: 9641087
    Abstract: A method and a device for detecting conduction mode is disclosed. The method uses an energy-storing element to connect with a synchronous rectifier and a load, and the load connects with the synchronous rectifier. Firstly, energy is discharged from the energy-storing element and applied to the load through the synchronous rectifier to periodically generate a detected voltage signal across the synchronous rectifier, and the detected voltage signal comprises at least one raising waveform, at least one horizontal waveform and at least one descending waveform. Then, an output is generated according to waveform of the detected voltage signal and either of a reference duration or a reference slope, so as to determine that the energy-storing element operates in CCM or DCM.
