Embodiments of this application provide a voltage conversion circuit, a control method, a DC/DC converter and a device. The voltage conversion circuit includes a failure isolation module, a soft start module, and a voltage conversion module. The voltage conversion module includes an output filter capacitor. Both a first terminal of the failure isolation module and a first terminal of the soft start module are connected to a positive electrode of a first battery, both a second terminal of the failure isolation module and a second terminal of the soft start module are connected to a first terminal of the output filter capacitor, and a second terminal of the output filter capacitor is connected to a negative electrode of the first battery. The soft start module is configured to connect the first battery and the output filter capacitor, so that the first battery charges the output filter capacitor.

Voltage conversion circuit, control method, DC/DC converter, and device

A method and a system for implementing time synchronization in a local area network are disclosed, and the local area network includes a master system device () and a slave system device (). The method includes: the master system device () synchronizing a local time according to a Universal Time Coordinated (UTC) time normally received from a Global Positioning System (GPS) satellite and a network clock aligned with the UTC time, and regularly broadcasting the local time to each network node which serves as the slave system device () and needs to perform time synchronization; and the slave system device () synchronously updating the local time according to the received local time of the maser system device () and a local network clock aligned with the network clock of the maser system device ().
