    摘要： This invention provides A Network Distributed Dynamic Equalized Power Supply Method, with the steps shown as below that: multiple High Voltage Direct Current power supply devices deployed in parallel, the entire High Voltage Direct Current power supply devices parallel connected via the Direct Current Power Grid; there being four power supply modes pre-set in each device, the initial setting part being that the power supply mode of back-up High Voltage Direct Current power supply device being mode B, and the rest being mode A, further, the power supply voltage of the entire High Voltage Direct Current power supply devices to the Direct Current Power Grid being the same. As per the operation status of one certain High Voltage Direct Current power supply device or the change of power supply load, the power supply mode of the mentioned High Voltage Direct Current power supply device and the power supply voltage to the Direct Current Power Grid are changed. By adopting the above-mentioned technology plan, the distributed power supply could be conducted and networked, and the reliability of the Network Distributed power supply could be improved, in the meantime, the electric quantity of power supply could be flexibly adjusted and distributed among the different power supply devices, to improve the efficient of the utilization of energy and reduce the energy consumption.

    摘要： A charging system and charging method for a tenninal (2), and a power adapter (1) and a switch power source. The switch power source comprises a first rectification unit (101), a switch unit (102), a transformer (103), a second rectification unit (104), a sampling unit (106) and a control unit (107), wherein the control unit (107) outputs a control signal to the switch unit (102) and adjusts a voltage of a first pulse waveform according to a voltage sampling value and/or a current sampling value sampled by the sampling unit (106) to obtain a primary sampling voltage, and adjusts a duty ratio of the control signal according to the primary sampling voltage, the voltage sampling value and/or the current sampling value, so that a voltage of a third pulse waveform satisfies a charging requirement. The switch power source can make an output voltage and current waveform change along with an input voltage and current waveform, so that a good power factor can be obtained. Moreover, when the switch power source is applied to the power adapter (1), a voltage of an output pulse waveform can be directly loaded to a battery of the device (2), so that miniaturization and low costs of the power adapter (1) can be realized.
