The invention belongs to the technical field of high-power microwaves, and discloses a large-caliber repetition-frequency pulse guide magnetic field device which comprises an upper computer, a remote controller, a charging switch, a discharging switch, a charger, an energy storage capacitor, a solenoid magnet, an energy feedback loop and an energy release loop. The device adopts a circuit topology with energy feedback, has the advantages of compact structure, low energy consumption, flexible and adjustable magnetic field and the like, and reduces the maintenance difficulty and operation cost of a high-power microwave source magnet system. According to the requirement of an over-mode high-power microwave generator for a guide magnetic field, the device realizes flexible and adjustable magnet aperture of 131 mm and magnetic field intensity below 1T, and can continuously work at a repetition frequency of 30 Hz, and the repetition precision is 0.2%. When the high-power microwave source is applied to a high-power
