Abstract

Method for contactlessly transmitting electrical energy to a load (17) using a transmission system (1), having the steps of: converting alternating current from an alternating current source (4) into direct current using a primary rectifier (5), converting the direct current generated by the primary rectifier (5) into alternating current using a primary inverter (7), changing a primary parameter (di) at a component (38) of a primary part (2) of the transmission system, such that the electrical power consumed by a load (17) is changed as a result, contactlessly transmitting the electrical energy of the alternating current generated by the primary inverter (7) from a primary coil (9) to a secondary coil (12), converting the alternating current generated in the secondary coil (12) into direct current using a secondary rectifier (15), changing a secondary parameter at a component (16) of a secondary part (3) of the transmission system (1), such that the electrical power consumed by the load (17) is changed as a result, supplying electrical energy as direct current to the load (17), wherein an A-efficiency of the contactless transmission of energy with respect to a secondary A-parameter…
