“…This paper uses series inductance to form an LC series resonant soft switching circuit to reduce circuit switching power loss, as shown in figures 3 and 4. The literature [28] demonstrates that a certain amount of inductance in series will not affect the discharging efficiency of DBDs, although certain condition will increase the discharging efficiency of DBDs. Then, i L can be calculated from the equivalent circuit:…”

For an all solid-state Marx modulator applied in dielectric barrier discharges (DBDs), hard switching results in a very low efficiency. In this paper, a series resonant soft switching circuit, which series an inductance with DBD capacitor, is proposed to reduce the power loss. The power loss of the all circuit status with hard switching was analyzed, and the maximum power loss occurred during discharging at the rising and falling edges. The power loss of the series resonant soft switching circuit was also presented. A comparative analysis of the two circuits determined that the soft switching circuit greatly reduced power loss. The experimental results also demonstrated that the soft switching circuit improved the power transmission efficiency of an all solid-state Marx modulator for DBDs by up to 3 times.

The purpose of impedance matching for a Marx generator and DBD lamp is to limit the output current of the Marx generator, provide a large discharge current at ignition, and obtain fast voltage rising/ falling edges and large overshoot. In this paper, different impedance matching circuits (series inductor, parallel capacitor, and series inductor combined with parallel capacitor) are analyzed. It demonstrates that a series inductor could limit the Marx current. However, the discharge current is also limited. A parallel capacitor could provide a large discharge current, but the Marx current is also enlarged. A series inductor combined with a parallel capacitor takes full advantage of the inductor and capacitor, and avoids their shortcomings. Therefore, it is a good solution. Experimental results match the theoretical analysis well and show that both the series inductor and parallel capacitor improve the performance of the system. However, the series inductor combined with the parallel capacitor has the best performance. Compared with driving the DBD lamp with a Marx generator directly, an increase of 97.3% in radiant power and an increase of 59.3% in system efficiency are achieved using this matching circuit.

“…24,25 Although this type of power supply has a compact structure, it is easy to cause a voltage oscillation on DBD loads, magnetic saturation of transformer and transformer heating fault. A bipolar pulsed excitation voltage on DBD loads can be generated with a power supply based on Marx circuits [26][27][28] or multilevel circuits. 29,30 This type of power supply has the advantages of modularization and step-less adjustment of working frequency, idle time, and voltage amplitude.…”

SummaryAn excitation voltage with a high rising rate, falling rate, and idle time simultaneously is beneficial to taking advantage of the potential of dielectric barrier discharge (DBD) loads. However, how to generate this kind of excitation voltage with a simple structure is rarely researched. To address the issue, a novel LC‐based bipolar high‐voltage pulsed power supply is proposed in this paper. The proposed power supply is comprised of an inductance, two capacitances, a step‐up transformer, and two power switches sharing the same ground. By planning the switch sequence of the two power switches, a resonant stage and an idle stage are formed. The resonant stage is used to generate a bipolar pulse excitation voltage on DBD excimer lamps and an idle time in the excitation voltage is generated in the idle stage. The characteristics and the parameters design of the proposed power supply are studied by theoretical analysis. To verify the feasibility of the proposed power supply, an experimental setup is built with a DBD‐type excimer lamp. The experimental results show that the power supply not only better takes advantage of the potential of DBD excimer lamps, but also there is a fine luminous regulation feature for the excimer lamp. Besides these characteristics, the proposed power supply has several other benefits, such as good adaptability to different DBD‐type excimer lamps, a small number of components, and high efficiency.
