Abstract
A resonator circuit for a contactless energy transmission system for charging electric vehicles and a contactless energy transmission system for charging electric vehicles are described. The resonator circuit may include first and second terminals, multiple windings, and first and second switching elements. The windings may be divided into first and second groups. A connection node may be arranged between the first and second groups of windings and connected via the first switching element to the first terminal, and the connection node is connected via the first group of windings to the second terminal. The second switching element may be arranged between the second group of windings and the first terminal. The first connection node may be formed in a star-shaped manner between the first group of windings, the second group of windings, and the first switching element.
