【 摘 要 】

In this paper, a new type of two-sources-driven underwater spark acoustic source (TSD-USAS), is suggested. Then, the main mechanism and design principle of the high-low-voltage-coupler, which is the key part of TSD-USAS, is discussed. Finally, an experimental measurement to the backward voltage-penetration of the high-low-voltage-coupler, is implemented (at conditions of the HV capacitor: C H = 1 μF, U 0 = 15 kV). The experimental results show that, when the HV discharge of the right-hand-side part (traditional USAS) leads to a non-breakdown, no apparent backward voltage-penetration will appear at the low voltage input terminal of the high-low-voltage-coupler; when leads to a breakdown, a backward voltage-penetration (peak value of +6200 V, pulse width of 17 μs) will arise.
