“…e CPA with such advantages as the high power density, high pulse discharge frequency, and easy waveform adjustment is also the preferred power source for engineering electromagnetic launching systems in the future [7]. e difference between the CPA and conventional generators is that the CPA works at the transient state and the magnetic flux in the air gap is compressed with a special compensating unit to reduce the inductance of armature winding, and thus a high pulse current whose peak is more than tens or even hundreds of kiloamperes can be generated instantaneously within 20 μs to 10 ms [8][9][10].…”

In the compensated pulsed alternator, the slotless armature winding and internal rotor structure with electric excitation are usually adopted. The above structure can effectively reduce the air gap leakage and has the simple structure, but it exhibits such disadvantages that the armature winding is difficult to disperse the heat and to be fixed, the shielding element is easy to deform due to the centrifugal force in the discharge process, and both reversing device and energy storage flywheel need to be used. In this investigation, an outer rotor permanent magnet passively compensated pulsed alternator was designed to solve the above problems. Then, a collaborative simulation model for the railgun system driven by outer rotor permanent magnet passively compensated pulsed alternator was built with the ANSYS simulation platform. The no-load characteristics of the alternator, the output characteristics of the alternator, and the performances of the railgun system were compared and analyzed under three kinds of pole and slot matching. The present research can provide the theoretical foundation and reference for the further engineering application of an outer rotor permanent magnet passively compensated pulsed alternator.
