Patent number: 11588380Abstract: In certain embodiments, a power generator has a rotor, a stator, a bridge rectifier, and one or more capacitors. The stator has one or more inductors that generate phased AC power when the rotor moves relative to the stator. The bridge rectifier, which is connected between the inductors and two output terminals of the power generator, converts the phased AC power into a DC output current at the two output terminals. The capacitors are connected to the inductors to electro-magnetically resonate when the rotor moves relative to the stator to increase peak amplitudes of the phased AC power and thereby increase the level of the DC output current. In certain applications, the increased. DC output current enables the power generator to charge a battery faster and more efficiently.Type: GrantFiled: September 23, 2019Date of Patent: February 21, 2023Assignee: Seabourne Solutions, LLCInventors: John A.
