This white paper is an adaptation of a prior conference paper available on our website a “A Versatile Marx Generator for Use in Directed Energy and Effects Testing” and has been updated to include more recent information on the APELC MG15-3C-940PF (MG15) Marx generator. The MG15 has become one of the most widely used Marx generators from our catalog because of its versatility, reliability, and ability to drive a 50 Ohm cable. The following paper provides greater detail on the specifications of the MG15 and why it has become so widely adopted by customers in need of a compact pulsed power system.
