System for contactless transmission of power, has transmitting side with power oscillator which oscillates freely with respect to frequency, and receiving side with resonant circuit unit and rectifier device

摘要

The system (10) has a transmitting side (12) and a receiving side (14). The transmitting side comprises a power oscillator (20) which oscillates freely with respect to frequency, and the receiving side comprises a resonant circuit unit (50) and a rectifier device (74). The power oscillator comprises a resonant circuit (22) with a coil (24) and a capacitor (26). The resonant circuit is provided with a central feed (36). The coil and capacitor are arranged in parallel. The power oscillator is designed as push-pull oscillator (44). An independent claim is included for a method for contactless energy transmission.
