Abstract	In order to find an applicable power supply used in electric guns, there have been two types of the magnetic flux compression linear generator (MFCLG) that use the solenoids as the stators. That is to say, a piston armature or a solenoid armature is used within the stator. Although they can amplify the current theoretically, they can only compress the component of the magnetic flux. So their efficiency is low, and there exist some difficulties, which is difficult to solve in terms of the engineering technology. In addition, the use of the solenoid armature leads to the increment of the ineffective part of the solenoid. A kind of the rail stator augmentation MFCLG is presented here. It separates the combustion chamber-cylinder and the generating channel into two independent parts, and with an antirecoil device. The combustion chamber is extended as a cylinder. Within it the piston pushes the stator-armature package to move forward through the connecting rod along the generating channel consisted of the rails. This can compress the magnetic flux to generate the large electric current to be used by electric guns. If we fill the integrated fuel into the combustion chamber, we can realize the successive pulse operation. The separation of the combustion chamber-cylinder and the channel can avoid the high temperature burning gases from entering the channel to cause ablation. The basic mathematic model of this type of the generator is given and its physical properties are analyzed in this paper. It is found that it can compress the magnetic flux perpendicularly and has higher efficiencies for compression and conversion. It can produce large current with sufficient pulse width to supply the electric guns. Besides, a self-excitation method for this type of generator is also put forward, which can omit the seed power source. Instead, it uses the chemical energy that drives and compresses the magnetic flux to generate the electric current to produce the initial seed magnetic flux used by it.
