Abstract

The invention relates to a series resonant DC/DC converter comprising:first DC terminals (T1P, T1N); second DC terminals (T2P, T2N); an inductor device (ID; TD); and a first switching circuit (SC1) connected between the first DC terminals (T1P, T1N) and the inductor device (ID; TD). The first switching circuit (SC1) comprises a first set (S1sc1; S1sc1, S4sc1) of switches and a second set (S2sc1; S2sc1, S3sc1) of switches. A second switching circuit (SC2) and a resonant circuit (RC) are connected between the second DC terminals (T2P, T2N) and the inductor device (ID; TD), where the second switching circuit (SC2) comprises a first set (S1sc2; S1sc2, S4sc2) of switches and a second set (S2sc2; S2sc2, S3sc2) of switches. A control circuit for controlling the set of switches of the first and second switching circuits (SC1, SC2) to control the current and/or voltage at either the first DC terminals (T1P, T1N) or the second DC terminals (T2P, T2N).
