Assignee: BRUSA ELEKTRONIK AG
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC B  H  Y | IPC B  H

Claim 0:
1. A base station for a power transmission system, the base station comprising:
a generator to generate a time-dependent power having a prescribable duty ratio and a prescribable frequency;
a primary circuit having a primary coil;
a primary measuring device to measure a real power and/or an apparent power in the primary circuit; and
a control device;
wherein the primary circuit is connected to the generator and to the primary measuring device;
wherein the control device is connected to the primary measuring device and to the generator;
wherein the control device is configured to keep the prescribable duty ratio constant while varying the prescribable frequency;
wherein the control device is configured to use the primary measuring device to measure the real power and/or the apparent power while varying the prescribable frequency from a starting frequency to an ending frequency in a range of descending frequencies;
wherein the control device is further configured to keep the prescribable frequency constant and vary the prescribable duty ratio when a prescribable real power limit value and/or apparent power limit value is/are exceeded; and
wherein the control device is further configured to exclude a prescribable combination of values for the prescribable frequency and the prescribable duty ratio when varying the prescribable frequency and/or when varying the prescribable duty ratio.
