Abstract (en)
[origin: WO2013104503A1] The invention relates to an inverter having at least two switching means (S1, S2, S3, S4) for feeding a resonant circuit (LS, CS) from a source (Uin, Izk), wherein a control unit of the inverter controls the switching means (S1, S2, S3, S4), characterized in that the control unit controls the switching means (S1, S2, S3, S4) in such a manner that in a first mode A, the inverter feeds the resonant circuit (LS, CS) via the switching means from the source (Uin, Izk), and in a second mode B, the resonant circuit (LS, CS) is decoupled from the source (Uin, Izk), wherein the control unit switches back and forth between the two modes A and B for adjusting a nominal voltage (Ip_soll) in the resonant circuit (LS, CS) or a nominal voltage (Up_soll) on the resonant circuit (LS, CS).
