The present application provides a multifunctional multi-port hybrid direct-current circuit breaker and a control method. The circuit breaker comprises: a power flow control module, a plurality of current conduction modules, a current limiting module, a power consumption module, an on/off module and a plurality of selection modules; one end of the power flow control module is connected to a direct-current bus wiring port, and the other end thereof is connected to one end of each current conduction module, the other end of each current conduction module is connected to a direct-current line wiring port, and the direct-current bus wiring ports and the direct-current line wiring ports are arranged in one-to-one correspondence; one end of each selection module is connected to a direct-current line corresponding thereto, and the other end thereof is connected to one end of the current limiting module; the other end of the current limiting module is respectively connected to one end of the energy consumption module and one end of the on/off module; and the other end of the energy consumption module and the other end of the on/off module are connected to a direct-current bus. By implementing the present application, the investment on a direct-current circuit breaker device is greatly reduced, and a power flow control capability is provided, facilitating to the development a multi-terminal and direct-current power grid.
