Abstract
A circuit arrangement (S) for supplying a load (P), whose essential electric property is capacitance, from a DC voltage source (U) has a switch element (S), which in the operational state is alternately switched between the conductive and non-conductive state, and at least one component (L, L) whose essential property is inductance, the load (P) being coupled into the circuit arrangement (S) in parallel to the component (L, L) so that the load (P) and the component (L, L) form a parallel resonant circuit, the switch element (S) is connected between the parallel resonant circuit and a base voltage (GND) and the DC voltage source is to be applied in parallel (U) to the load. The circuit arrangement (S) according to the invention can be used to drive the capacitive load (P) in a bipolar manner, the supply of the load in the non-conductive phase of the switch element (S) being achieved by the component (L, L).
