Transfer efficiency of linear transformer driver affected by load impedance

Through the theoretical analysis and simulation, the effects of impedance on the voltage transfer efficiency, energy transfer efficiency and peak power transfer efficiency when pulse forming network (PFN) discharges to the load directly and through the linear transformer driver (LTD) are discussed. Based on the one-stage LTD module, a series of experiments are carried out by changing the impedance of the load. The experiment show that the maximal energy transfer efficiency of 80.5% is achieved when the impedance of the load equals to the 2.5 Ω impedance of the PFN, with voltage transfer efficiency and peak power transfer efficiency being 84.1% and 73.9% respectively. The voltage transfer efficiency would increase to 99.0% when the impedance of load is 3.4 Ω, with voltage transfer efficie
