Abstract

The present invention discloses a resonant energy compensation circuit structure and operating method for a multi-stage coil electromagnetic gun. The circuit structure includes a first main energy storage unit with polarity, a first fully controlled switch, a first freewheeling diode, and at least one group of acceleration networks. The acceleration network includes a multi-stage first acceleration circuit, a second acceleration circuit, a non-polar auxiliary energy storage unit, or may also include a second main energy storage unit and a second freewheeling diode. By controlling the cyclic operation of multiple groups of acceleration networks, and in each round of circulation, each group of acceleration networks first turns on the first acceleration circuit of one level in turn, and then turns on the second acceleration circuit of one level in turn. The present invention can design a multi-stage electromagnetic gun using a small number of components, and the circuit structure is compact, lightweight, and portable. The present invention uses high-voltage film capacitors to participate in energy recovery and release, which can improve the transmission power and efficiency of the multi-stage electromagnetic gun.
