With the advancements in power semiconductors and converters, power electronics based high-voltage pulse generators (HVPG) have emerged due to their advantages of high repetition rate, flexible control, long lifetime, and compact size. However, there is a lack of comprehensive literature review on recent advances in power electronics intensive HVPG technologies. To fill this gap, we present a systematic review on HVPGs. First, HVPGs are classified into different types based on their mechanisms. Each type along with its basic circuits and modifications are introduced. Then, the characteristics, advantages, and disadvantages of these topologies are summarized. Furthermore, the potential applications of HVPGs are explored. The performance of pulse generators mentioned in the literature and commercial products is listed. Finally, future trends and technical challenges in HVPG design and development are discussed. This paper provides a clear understanding of HVPGs and the inspiration of topologies developments to meet the specific requirements. Current state and potential future directions are discussed and summarized to facilitate evolvements in HVPG technology.INDEX TERMS Pulsed power supply, high voltage, pulse generator, power electronics.

“…A CVL discharge tube (36 mm and 1.8 m long) in leakfree condition delivers an average output power of 30 W (plane-plane resonator configuration) and serves as the load to the pulse power supply. The complete details of the PGU, the laser head and the measurement setup are reported in detail in our previous publications [14][15][16][17]. A schematic of the pulse discharge circuit and the laser head is shown in figure 1.…”

“…The figure 1(b) shows the approximate equivalent electrical parameters of the CVL. The PGU consists of a resonant charging circuit, pulse transformer, Insulated Gate Bipolar Transistor (IGBT) and the magnetic pulse compression (MPC) stages [15]. The pulse voltage across the laser head is 13 kV and the pulse current through the laser head is in the order of 450-500 A, depending on the laser head discharge condition [14,17].…”

“…The pins facilitate the discharge during initial condition due to the sharp edges, which intensify the electric field; thus, pins are used in the laser electrodes. In previous reports [14,15], we presented the impact of different pin configurations on the laser performance. It has been shown that the electrode pin configuration has an immense impact on the phantom current in the metal vapor laser [14].…”

In the pursuit to analyze the impedance of copper vapor lasers (CVLs) in different conditions, a novel approach has been proposed in this paper. The underdamped behavior of the voltage waveform across the CVL is leveraged to compute the impedance of high-voltage discharge plasma in the laser. This methodology provides an accurate idea of the discharge plasma resistance and inductance as it is calculated on the basis of experimental voltage waveforms obtained from the laser system. The laser head inductance remains almost fixed and equivalent to ∼0.47 µH whereas the laser resistance changes between 34 Ω and 11 Ω depending on the discharge condition and its constituents. A critical evaluation of CVL impedance is done in all experimentally possible conditions, and a methodology has been proposed to maintain the CVL impedance, which results in the power stability of the laser in oscillator–amplifier configuration. The laser impedance variation w.r.t. time, pressure, operating voltage and electrode pin configuration has been investigated. The impact of the localized electric field at the electrode on the laser resistance has also been emphasized in this paper. A good concurrence exists between the calculated laser impedance and its experimental behavior.
