Research on the Excitation Control of Brushless Doubly-Fed Alternator in a Novel Pulse Capacitor Charge Power Supply

Brushless doubly-fed alternator (BDFA) has good application prospects in pulsed alternator. It works through the rotor's pole pairs transformation function to get excitation indirectly. Since there are no brush and slip ring, BDFA is expected to have high reliability and long service life. This paper studies on the excitation control of BDFA in pulse capacitor charge power supply system. A mathema...
