A bidirectional DC/DC converter includes a first terminal circuit, a transformer, a second terminal circuit, and a reset circuit, and the transformer includes a first winding and a second winding. The first terminal circuit is coupled to the first winding, and the second terminal circuit and the reset circuit are coupled to the second winding. In a first time period in which the bidirectional DC/DC converter is in a second working state, the second terminal circuit transmits a second alternating current to the first terminal circuit by using the second winding and the first winding; and in a second time period in which the bidirectional DC/DC converter is in the second working state, the reset circuit is in a conducted state, to reset the second winding.

A device and method of driving multi-Packet Data Protocol (PDP) data communication for a mobile broadband device are disclosed. The device includes: a Radio Interface Layer (RIL) module which is configured to receive a function call request message based on data or a configuration service, and call a PDP management module through an extended multi-PDP support interface; a PDP management module, which is configured to acquire a PDP type of an access device corresponding to the function call request and currently supported by the system, trigger a PDP control module, and update and maintain a PDP resource state table; a PDP control module which is configured to encapsulate the function call request message into a Qualcomm MSM Interface (QMI) instruction or covert it into an AT instruction, carry in the instruction identifier information of the access device and output the instruction to a device management module; and a device management module, which is configured to send the instruction to the corresponding access device to perform PDP setup. The present disclosure is capable of supporting a multi-PDP data communication mode and increasing the access speed for a radio broadband device.
