Plasma Gun Breakdown Power Supply (BSD)

Plasma guns serve as pivotal components for pre-ionization, fueling, and physical control in fusion devices. Their power supply systems must withstand the challenges of drastic transient impedance fluctuations, transitioning rapidly from high-voltage breakdown to high-current conduction. To meet these rigorous requirements, Startorus Fusion has developed this specialized power supply. By integrating all-solid-state switching and optical-isolation triggering technologies, the system achieves nanosecond-level precision control and superior high-voltage isolation for enhanced noise immunity. The optimized low-inductance loop design effectively suppresses voltage spikes and current surges during the breakdown phase. Furthermore, the dual-capacitor redundant architecture and multi-layered protection mechanisms ensure stable and reliable operation throughout the hydrogen discharge process. While maintaining system safety and signal integrity, the power supply delivers stable high-power pulse energy with precise waveform modulation, providing critical mission-power support for fusion experiments.
