A driver configuration management method may be applied to a management device and includes determining target information, where the target information is used to represent a computing capability of an electronic device; converting, based on the target information, a configuration source file into a target configuration file that uses a target file format; and sending the target configuration file to the electronic device. The method may be applied to a scenario in which the management device generates and sends configuration files in different formats for electronic devices having different computing capabilities.

An adaptive dead time (ADT) control scheme for use with a switch mode power converter having a full bridge with synchronous rectifiers topology. A controller which implements the control scheme includes an input circuit arranged to receive a signal representative of the converter's output voltage, and an output circuit arranged to operate the converter's switching elements and synchronous rectifiers to produce a desired output voltage. The controller is further arranged such that the converter's 'dead time' is adaptively varied in an inverse relationship to the magnitude of the load current. In a preferred embodiment, the signals used to operate the synchronous rectifiers are PWM signals, and the controller adaptively varies the dead time in a linear inverse relationship to the magnitude of the load current by modulating the rising and falling edges of the signals used to operate the synchronous rectifiers.

A resonant converter for improving synchronous rectification control is provided. The resonant converter obtains an input power, and through a switch unit, the period of the input power to be transmitted to a resonant circuit can be modified. The resonant converter further includes two transformers electrically connected to the resonant circuit, two synchronous controllers electrically connected to the primary sides of two transformers respectively, and two synchronous rectifiers electrically connected to the secondary sides of two transformers. The input power modified by the resonant circuit is obtained by the primary sides of two transformers, and two induced power are respectively produced at the secondary sides. Then, through sensing the polarity variation of the voltage, the two synchronous controllers individually provide a synchronous driving signal. Furthermore, the synchronous driving signals respectively drive two synchronous rectifiers to conduct alternatively, so as to rectify the induced power to the output terminal.
