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.
