Claim Text:
1. A supply circuit comprising: a bridge circuit comprising a first switch and a second switch, wherein each of the first and second switches has at least a first terminal and a second terminal, and wherein said first switch and said second switch are connected in series by a connection of said second terminal of said first switch with said first terminal of said second switch, and forming an interconnection therebetween, and wherein said bridge circuit is coupled to a load circuit; a resonant circuit, having a resonant capacitance and a resonant frequency, coupled at one end to a power source and coupled at another end to the interconnection of the first and second switches of the bridge circuit, wherein the resonant circuit is a series resonant circuit comprising an inductance and the resonant capacitance, wherein the resonant capacitance is divided into a first partial capacitance and a second partial capacitance, the first and second partial capacitances each comprising half of the resonant capacitance, wherein the first partial capacitance comprises a first capacitor and a second capacitor coupled to an interconnection between a first diode and the power source, and wherein the second partial capacitance comprises the first capacitor and a third capacitor coupled to an interconnection between a second diode and the power source; the first diode being coupled in series with the first switch at the first terminal of the first switch, with reference to the power source, and forming the interconnection between the first diode and said power source; the second diode being coupled in series with the second switch at the second terminal of the second switch, with reference to the power source, and forming the interconnection between the second diode and said power source; and a control unit configured or programmed to:
