Abstract: The present embodiments relate generally to DC-DC converters and more particularly to a scheme for providing current sharing between parallel converters in a multiphase configuration. In some embodiments, a cycle-by-cycle instant correction to the compensation signal offset is provided based on the current share error between the paralleled converters so as to achieve improved instant current share performance.

Abstract: A power converter comprises an input port configured to receive a source of power, an output port configured to provide output power, and a bridge circuit coupled to the input port. The bridge circuit comprises a first switch coupled in series with a second switch, and a third switch coupled in series with a fourth switch. A first clamp rectifier is coupled in series with a second clamp rectifier, and the first and second clamp rectifiers are coupled in parallel with the first and second switches. A first clamp capacitor is coupled between the first and second clamp rectifiers, with the first clamp capacitor operative to reduce power loss in the first and second clamp rectifiers. A first resonant inductor is coupled between the first and second switches. The power converter also includes a transformer operatively coupled to the bridge circuit, with the transformer comprising a primary winding and at least one secondary winding.

Abstract: An automatic-switching wireless communication system and method, comprising: a first device, and a second device. The first device verifies if said second device has paired with itself through using near end wireless communication. If an answer is positive, the second device connects with the first device by near end wireless communication and requests first device to activate remote end wireless communication. Then, second device searches to find a remote end wireless communication module of the first device. In case it is found, the first device is used as a wireless base station, such that the first device and the second device transmit data by remote end wireless communication, and the second device is connected to an outside network through the first device. If the second device is outside a range of the near end wireless communication of the first device, said remote end wireless communication module is closed automatically.
