Method for controlling the energy transfer between two resonators of a system for contactless energy transmission, and resonator device

A method for controlling the energy transmitted between two resonators of a system for contactless energy transmission comprises controlling the transmission power of a transmitter resonator contained in a primary part of the system. This is excited to oscillations with excitation pulses from a direct voltage source with approximately constant voltage. The generation of the excitation pulses and their frequency takes place depending on the required transmission power.
