Research on Composite Energy Storage and Impedance Matching Strategies for Variable Load Pulse Acoustic Transmitters

A composite energy storage and adaptive impedance matching strategy was proposed in order to reduce the power capacity requirements of pulse acoustic transmitters. The composite energy storage system was composed of lithium-ion batteries and supercapacitors, and the state of the energy storage system was estimated based on external characteristic parameters. The energy distribution was dynamically adjusted according to the overall transmitter source demand; An adaptive impedance matching network was designed for load transducers under different hydrostatic pressures, optimized broadband matching topology parameters, and dynamically adjusted the matching network based on hydrostatic pressure feedback; Through verification under different operating conditions, the results show that the composite energy storage and impedance matching strategy can improve the system power factor, reduce the apparent power demand and the energy storage design capacity. The proposed method has high engineering practical value and can be used as an effective energy system design method.
