A resonant converter for supplying an electrical consumer (D), wherein the input circuit of the resonant converter forms a voltage centre (N) which is connected through a self-inductance (L1) to a first node (B), from which there is a connection through capacitors (C1, C2) to a positive supply potential and a negative supply potential, wherein the self-inductance (L1) is magnetically coupled to a magnetizing device (Ls) which is magnetized in alternating directions by means of an electronic circuit (I pulse). The resonant converter has the characteristic that the first node (B) is connected via the self-inductance (L1) to the voltage centre (N) which is in direct connection with a first set of electronic switches (S3, S4), which set up a connection to at least one output (D) when the switches (S3, S4) are closed, wherein the positive (A) supply voltage and the negative (B) supply voltage, respectively, are connected to the output (D) through a second set of electronic switches (S1, S2), wherein the electronic switches (S1, S2, S3, S4) are opened and closed in dependence on an overall control system. This makes it possible to provide a resonant converter with the smallest possible power loss. |
