Modeling and Analysis of High Gain Pulse Generator for Hydrocarbon Synthesis from CO₂

Plasma technology for CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> conversion is attracting increasing interest due to its operation under mild conditions and its potential to convert CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> into valuable compounds and renewable fuels efficiently. Among the plasma technologies available, the gliding arc plasmatron (GAP) technique, in particular, is effective for breaking CO<inf xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</inf> molecules and requires short, high-voltage pulses to achieve this. This paper proposes a full-bridge resonant boost converter designed to deliver pulse high voltage with high pulse repetition rates, lower (full width at half maximum) FWHM, and high efficiency. The modeling of this topology is essential for performance prediction, design op-timization, reliability assessment, cost reduction, control strategy development, and understanding dynamic behavior. Hence, this paper offers a detailed discussion on the converter’s operation, modeling, and simulation, including all significant parasitics. The full-bridge resonant converter is simulated to achieve a peak pulse voltage of 10 kV, a pulse repetition rate of 15 kHz, and a pulse width (FWHM) of 4 μs.
