Patent attributes
An AC unipolar generator provides high power at high frequencies without requiring a source of high-frequency mechanical power. A rotor having a plurality of spaced magnetic disks and two sets of rotating capacitor plates is coupled to a source of mechanical power, the two sets of rotating capacitor plates being spaced apart along the outside of the rotor and electrically connected via a conducting channel. A stator surrounding a portion of the rotor that includes the magnetic disks and one of the two sets of rotating capacitor plates includes a magnetic stator core that forms a magnetic circuit with the magnetic disks of the rotor, a stator field coil, and a fixed set of capacitor plates that capacitively couple the stator field coil to the rotor conducting channel through one of the sets of rotating capacitor plates. A second fixed set of capacitor plates located outside of the stator capacitively couples the rotor conducting channel back to the stator field coil through the other set of rotating capacitor plates. The stator field coil and the two sets of capacitor plates form a resonant LC circuit that characterizes the AC frequency of the power generated by the generator.
