| 摘要 |
The invention relates to a device for the inductive transfer of electric energy from a stationary unit having a current supply device and a primary inductance which is connected thereto, to a vehicle that is adjacent to said unit and has a secondary inductance. The vehicle has a secondary control element for adjusting the secondary power taken from the secondary inductance and comprises a control device, said control device enabling the withdrawn secondary power to be modified in steps. Said stationary unit comprises a primary control element for adjusting the primary power which can be injected into the primary inductance, which contains a first measuring device, said measuring device enabling an operational parameter, influenced by the secondary power, of the current supply device to be measured. The primary control element adjusts the primary power which can be injected in accordance with modifications of the operational parameter measured by the first measuring device. The secondary power can be switched preferably between two steps by the switching device and has in one of the steps, a value which is at least approximately zero. |
