In this paper, a 50 MW two-phase passive compensated pulsed alternator(PCPA) is designed, some key technologies such as air-gap windings and end-turns shield are discussed in the design. Simultaneity, the current pulse shapes are simulated when the PCPA drives the electro-thermal-chemical gun(ETCG), and the factors which affect the current pulse shape are analyzed, and some methods to modify the pulse shape are presented. All of these will give reference to PCPA manufacture and discharge system experimentation.
