Experimental data for the acceleration of plate liners with a magnetic flux electromagnetic compressor are reported. The compressor is designed for peaking the power of current pulses with an initial amplitude of 3 MA. The compression zone of the liner has the form of a stripline, which makes it possible to use one current source both for the acceleration of the liner and for the generation of a magnetic flux in the compression zone. The acceleration dynamics and the deformation of plate liners during an operating cycle of the compressor are studied. In the experiments conducted, the compressor is powered by a capacitor battery. The current amplitude in the output capacitive load rises by 1.6 times, while the pulse narrows twofold. Experimental data are compared with numerical calculation data for the liner material flow, which are found to adequately describe processes taking place in such a compressor.
