Abstract :
The concept and relevance of power factor is presented in the context of high-performance EM launchers. As the scale of launchers grows and efforts to improve efficiency continue, power factor considerations will become crucial in engineering design and ultimate launcher performance limits. The use of motion-induced commutation to improve the power factor are discussed. Various approaches to inductive commutation are presented, including the brush-commutated 9 MJ coilgun, the solid state-switched coilgun, and the quenchgun
