To improve the charging speed of an underwater wireless power transfer system, this paper proposed a non-tunable matching circuit. First, the load condition of the matching circuit was derived from the relationship between the matching circuit and charging time during matching at each charging voltage of the battery. Based on the conditions derived, the rectifier and battery were equivalently converted to passive elements. We performed circuit analysis and found that these elements were very low impedance, and small deviations in the values led to large design errors. Finally, we eliminated the discrepancy and designed the non-tunable matching circuit. |
