Abstract
Method for contactlessly transmitting electrical energy to a load () using a transmission system (), having the steps of: converting alternating current from an alternating current source () into direct current using a primary rectifier (), converting the direct current generated by the primary rectifier () into alternating current using a primary inverter (), changing a primary parameter (di) at a component () of a primary part () of the transmission system, such that the electrical power consumed by a load () is changed as a result, contactlessly transmitting the electrical energy of the alternating current generated by the primary inverter () from a primary coil () to a secondary coil (), converting the alternating current generated in the secondary coil () into direct current using a secondary rectifier (), changing a secondary parameter at a component () of a secondary part () of the transmission system (), such that the electrical power consumed by the load () is changed as a result, supplying electrical energy as direct current to the load (), wherein an A-efficiency of the contactless transmission of energy with respect to a secondary A-parameter is determined, the secondary parameter is then changed from the secondary A-parameter to at least one secondary B-parameter and a B-efficiency is determined for the at least one secondary B-parameter, and that efficiency with the maximum efficiency is selected from the A-efficiency and from the at least one B-efficiency and this selected maximum efficiency is referred to as C-efficiency, and energy is then contactlessly transmitted with a secondary C-parameter assigned to the C-efficiency as an iteration step for determining the secondary C-parameter.
