Inductance Mathematic Model of a Homopolar Inductor Alternator in a Novel Pulse Capacitor Charge Power Supply

The investigation of inductance mathematic model of a homopolar inductor alternator (HIA) in a novel pulse-capacitor charge power supply (CCPS) is presented. We study the characteristics of the inductance parameters based on the HIA theory and 3-D finite element analysis, establish the inductance mathematics model of HIA, and build a novel pulse-CCPS with 12/10-pole HIA. We also establish the simulation model of the power supply and compare the simulation results with the experimental one. The results prove the correctness of the inductance mathematic model. Finally, the problem of parameters-matching between the charging circuit and the HIA inductance is discussed.

I. Introduction

The primary energy of a traditional capacitor charge power supply (CCPS) system is provided by the grid. These power supplies have their advantages, but they can no longer meet the requirements of mobile supplies [1]. Recently, the rotating electrical machine has been proved to be a feasible pulse power supply and successfully applied in laser flash lamps, electromagnetic rail guns, and other devices [2]. A new type of pulse-CCPS system with a high-voltage generator-homopolar inductor alternator (HIA) has been researched [3], [4], and the design of the HIA is figured out [5], [6].
