Abstract: To address the limitations of conventional Bouncer modulators, including single-circuit topology, poor voltage scalability, and bulky resonant components, an improved long-pulse droop compensation technical architecture based on modular cascaded architecture is proposed. By constructing a series-connected structure comprising ‘n’ independent Bouncer energy storage control modules and integrating distributed charging isolation units with synchronized timing control strategies, flexible voltage scalability is achieved. This topology reduces the voltage requirements of both the main circuit power supply and the compensation power supply to 1/n of conventional solutions. The inductance value and voltage withstand requirements of the resonant inductor are also proportionally reduced to 1/n. Experimental verification on a test platform demonstrates that under conditions of 1ms pulse width and 50kV peak voltage, with 5 cascaded modules, the main circuit power supply voltage requirement for each module is only 10kV, and the compensation power supply voltage requirement is 2kV. The system complexity is significantly reduced and engineering feasibility is remarkably enhanced, with volume and weight being 40% lower than traditional designs. This technology breaks through the technical bottlenecks of traditional Bouncer modulators, providing a novel solution for long-pulse power systems in highly mobile platforms.
