Energy transfer efficiency for magnetic core of linear transformer driver

Magnetic core, an important part of linear transformer driver(LTD), can transfer energy from the primary side to the secondary and add induction voltage on it. So energy transfer efficiency of the core can affect efficiency, volume and weight of LTD system obviously. Factors impacting the energy transfer efficiency are primarily analyzed, and magnetic curve and energy loss are simulated by the non-linear magnetic core model of PSpice. Relative experiments are conducted, which demonstrates that the energy transfer efficiency is above 60% on 2.8 Ω load when the core working under the pulse of 20 kV, 220 ns.
