Study Of Capacitor Charge Power Supply With Homopolar Inductor Alternator: System Modelling And Mode Analysis

Capacitor charge power supply (CCPS) based on homopolar inductor alternator (HIA) has been successfully used in capacitor-based pulsed power supply (PPS), but there is still no perfect system modelling and compete system parameter design method. In this study, the system modelling and mode analysis of HIA-CCPS is developed in detail. First, a simplified CCPS model is proposed based on the voltage-behind-reactance (VBR) model of HIA and the phase base-value system (PBVS). Second, four different modes of CCPS are derived on conditions of the constant voltage load (CVL) assumption; the symbols and terms in these modes are unified. The equations derived in this study are the basis of the system parameter design and the further research of HIA-CCPS.
