AbstractAn inductively coupled power distribution system for moving vehicles, in which resonating primary circuits to distribute power for resonating secondary circuits to collect and use in an optimized manner. In order to have all circuits resonating at substantially the same frequency, devices which detect and adjust resonating components are used, such as a frequency drift compensator in which the present frequency is compared to a reference voltage and causes a driver to be ON or OFF accordingly. Switches are driven CLOSED or OPEN respectively and when CLOSED, supplementary capacitors are included with a main capacitor in a primary resonant circuit. Dithering or pulsed control provides a continuous control of resonance, as the system takes some milliseconds to respond.
