The Resonant Charging Chokes restrict amps through Inductive Reactance, which is dependent on the Frequency and the Inductance.

Increasing Frequency Increases Inductive Reactance

Decreasing Frequency Decreases Inductive Reactance

More Inductive Reactance Restricts More Amps

Less Inductive Reactance Restricts Less Amps
