Design and Analysis of a Pulse Capacitor Charge Power Supply System Based On Novel Brushless Field Assisted Induction Generator with Flux Control Capability

This study presents design and analysis of a pulse capacitor charge power supply (CCPS) system by employing a novel brushless field assisted induction generator (BFAIG). Unlike the conventional induction generators, in the proposed configuration of this study, in addition to the phase windings, the stator utilises an assisted DC field coil, which is responsible for production of controllable flux inside the machine. As the main salient feature of including the DC field coil which increases controllability of the flux, providing a regulated terminal voltage in a very wide range appropriate for CCPS applications can be pointed out. In addition, due to the lack of brush and winding on the rotor in the proposed BFAIG, stability, long life and high reliability can be addressed as appropriate characteristics of this structure. Moreover, in this study, analytical design of the proposed BFAIG is presented and two-dimensional magnetic-field distribution is performed by using MagNet CAD package to verify the design procedure. On the basis of obtained results from electromagnetic-field analysis, a CCPS is simulated and studied. The simulation results confirm the performance and efficiency of the presented CCPS.
