Disclosed in the present invention are a resonance device suitable for a miniaturized multistage electromagnetic gun, and an operation method for the resonance device. The resonance device comprises an energy storage unit, a resonance unit, a first switch circuit, a second switch circuit, and at least one stage of acceleration circuit; the acceleration circuit comprises a first oscillation branch and a second oscillation branch; the first oscillation branches of the stages of acceleration circuits are connected in parallel and then are connected in series to the resonance unit and the first switch circuit to form a first loop; the second oscillation branches of the stages of acceleration circuits are connected in parallel and then are connected in series to the resonance unit and the second switch circuit to form a second loop; and the first loop and the second loop are connected in parallel to two ends of the energy storage unit. Such a design simplifies the structure and circuitry of the device, and provides theoretical support for miniaturization design. The first switch circuit and the second switch circuit are alternately switched on and off, so that the acceleration circuit can be ensured to be always provided with a working oscillation branch. By multiplexing the resonance unit, energy recovery is carried out during resonance, thereby improving the energy conversion efficiency.
