Abstract: A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

Abstract: A computer obtains language configuration and language tags of a webpage in a browser. The computer searches for a language file in the computer according to the language configuration, and replaces the language tags in the webpage with the language tags in the language file. The computer obtains a serial number of the database according to the language configuration, and connects to the database according to the serial number of the database and displays data from the database in the webpage.

Abstract: A method for managing tags of virtual machines in a server involves presetting tags of the virtual machines. The preset tags include system tags and customized tags. The system tags and the customized tags carry out preset functions. The method further involves receiving a query request of a specified tag from a client computer, obtaining a specified virtual machine and one or more preset functions corresponding to the specified tag, and transmitting the specified virtual machine and the one or more preset functions corresponding to the specified tag to the client computer.
