“…As a result, the BTL is an important technology for high-power square pulse generation, pulse shaping and modulation [15,16]. Figure 1(a) shows the typical pulse modulation schematic based on a BTL and a saturable pulse transformer (SPT) [19,20]. The BTL usually consists of two single transmission lines such as the inner line and the outer line with electrical lengths as τ in and τ out (τ in = τ out ), and characteristic impedances as Z in and Z out , respectively.…”

Abstract-The Blumlein transmission line (BTL) has broad applications in pulse modulation, microwave technology and pulsed power technology. In this paper, a new theoretical method for variable reflection and transmission of electromagnetic waves at the inductive port of transmission line is put forward, in order to analyze the wave reflection characteristics of BTL at the inductive port formed by a saturated magnetic switch. At the inductive port, the variable reflection and transmission mechanisms of the voltage waves traveling through the BTL are analyzed in detail, and the inductive effects on the square voltage pulse of load formed by the BTL are also studied. Simulation and experimental results both demonstrated the proposed new theoretical method which shows great value on highpower microwave technology, high-power pulse forming, pulse shaping and modulation.

As a combination device of pulse transformer and magnetic switch, saturable pulse transformer (SPT) is widely employed in high power laser pumping and pulsed power technology. A reversed magnetic coupling mechanism of the diverging magnetic fields among multiple windings is put forward to explain the physical suppression effect on the saturation inductance of the SPT windings. The theoretical and experimental results reveal that the saturation inductance of the SPT can decrease to a level less than its structural inductance through regulating the reversed currents in the multiple windings, which helps to achieve a magnetic switch with ultra-low saturation inductance.

A pulse transformer has advantages of compactness and long lifetime achievability, and is considered an important candidate for the development of high voltage pulse generators. In this paper, a fast rise time high voltage pulse transformer with a compact structure is studied numerically and experimentally. Specifically, the structure of the pulse transformer was designed with paralleled winding groups. The response and insulation characteristics of the pulse transformer are investigated numerically. After that, a fast rise time high voltage pulse transformer was built, and scaling experiments were performed to analyze the influence of the feed structure of the pulse transformer. Importantly, the pulse transformer was successfully used in a low impedance generator, and high voltage pulses with a peak voltage of about 260 kV, a pulse duration of 170 ns, and a rise time of 65 ns were achieved on a resistive load of 32 Ω. The ratio of the transformer is approximately 1:3. Experiments show reasonable agreement with the numerical analysis.
