Abstract: The present invention is proposed to improve a conventional two-pin charging device (dumb charger), which stops charging when the battery is fully charged and can avoid the inrush current at any charging stage. A novel intelligent securely charging system is proposed, which includes a control module for controlling the operation of the system, a power conversion module for converting the input AC power ACin into the electricity required by the system, a switch module for passing or interrupting electrical power transformation, and a pre-charging module with impedance higher than the switch module used for limiting the inrush current, and a voltage detection module which detects the battery voltage Vb, the charging voltage Va. Further, the pre-charging module maintains in the on-state at any charging stage, and the switching module is configured to be in the on-state or off-state according to the application of the charging stage.

Abstract: The present invention proposes a parallel multi-source power supply system with unified output, which includes the first power supply having the first and the second USB-C connectors, the second power supply having the third USB-C connector electrically connected to the first power supply in parallel through the second USB-C connector. The first power supply is configured to operate in a constant current and constant voltage (CCCV) mode to output the first power, while the second power supply is configured to operate in a constant voltage (CV) mode to output the second power. The second power is transferred to the first power supply and unified with the first power to power an external electronic system through the unified output. The amount of the second power transferred to the first power supply is determined by a charging agreement through communicating between the first power supply and the external electronic system.
