Abstract

A converter including at least one DC/AC stage configured for generating a medium frequency AC power and having first and second AC outputs for the medium frequency AC power, at least one AC/DC stage configured for generating a DC power from the medium frequency AC power and having first and second AC inputs for the medium frequency AC power, and a resonant circuit provided between the DC/AC stage and the AC/DC stage and configured for transferring the medium frequency AC power. The resonant circuit includes at least two capacitors including a first capacitor and a second capacitor. The first capacitor is connected between the first AC output and the first AC input, and the second capacitor is connected between the second AC output and the second AC input. The resonant circuit further includes at least two inductors including a first inductor and a second inductor connected in series and defining a connection point between the two inductors. In a first alternative, the first inductor is connected in series between the first capacitor and the first AC input, and the second inductor is connected in series between the first AC input and the second AC input. In a second alternative, the first inductor is connected in series between the first capacitor and the first AC output, and the second inductor is connected in series between the first AC output and the second AC output. The at least two capacitors provide galvanic insulation between the DC/AC stage and the AC/DC stage.
