A multi-channel isolation bidirectional direct-current transmission circuit consists of a fourth transduction unit (4), a fifth transduction unit (5), a sixth transduction unit (6), a seventh transduction unit (7), magnetic coupling devices (10), a control circuit (8) and an impulse source (9). The impulse source (9) is connected with the fourth transduction unit (4), the fifth transduction unit (5), the sixth transduction unit (6) and the seventh transduction unit (7) and exerts synchronizing impulse. The control circuit (8) is connected with the fourth transduction unit (4), the fifth transduction unit (5), the sixth transduction unit (6) and the seventh transduction unit (7) and exerts a gating signal. The fourth transduction unit (4), the fifth transduction unit (5), the sixth transduction unit (6) and the seventh transduction unit (7) are mutually connected through the magnetic coupling devices (10), and mutual transmission of electric energy among the units on which the gating signal is exerted is achieved. The multi-channel isolation bidirectional direct-current transmission circuit is simple in structure, and the problems including complicated circuit, high cost and poor reliability are solved.
Description
1 Technical field [0001] The invention relates to a multi-channel isolated bidirectional direct current transmission circuit, which is a circuit for realizing bidirectional direct current transmission between any ports of multiple ports with different grounds, and belongs to the technical field of direct current power conversion. 2 Technical background [0002] In some DC power applications, multiple DC power supply units with different grounds are combined to jointly provide power output. In order to improve the overall output performance, the voltage of each DC power supply unit needs to be detected, and according to the detection result, the electric energy is transmitted among the selected units. [0003] Since each DC power supply unit does not share the same ground, the existing technology uses circuits such as switch switching, linear optical isolation, or front-end digitalization to realize voltage detection, and uses circuits such as capacitor networks, inductance n...
