Abstract
An inductive power transfer system including a synchronous drive system having a resonance control module. The resonance control module includes a primary coil module with a primary LC circuit. The resonance control module seeks and detects the resonant frequency of the primary LC circuit. The synchronous drive system further includes a switching coil amplifier for selectively energizing the primary coil to keep the primary LC circuit operating at or as close as possible to its natural resonant frequency. The inductive power transfer system may further include a secondary receiving unit. The secondary receiving unit includes a secondary LC circuit coupled with the primary LC circuit for inductively receiving power. The secondary LC circuit includes an LC filter and a rectifier unit for operating the secondary LC circuit at a mutual resonance with the primary LC circuit.
