Supply circuits (1-3,101-102,201-203) for supplying output current signals to loads (6,106,206) and comprising first circuits (1,101,201) with transistors (11-14,111-112,211-212) for converting input voltage signals into pulse signals and comprising second circuits (2,102,202) with resonance circuits for receiving the pulse signals and for supplying the output current signals to the loads (6,106,206) are provided with third circuits (3,203) for controlling the first circuits (1,101,201), which third circuits (3,203) comprise generators (35-37) for generating control signals for controlling the transistors (11-14,111-112,211-212) for reducing dependencies between the input voltage signals and the output current signals. The third circuits (3,203) supply the control signals in dependence of the input voltage signals and independently from the output current signals. The transistors (11-14,111-112,211-212) may form a full bridge, a full bridge operated in a half bridge mode, or a half bridge.
