Patent ID: 8716987

Claim:
A power supply arrangement comprising: an input for connecting a voltage source; a capacitor having an internal resistance; a means for charging the capacitor, said means for charging the capacitor coupling the capacitor to the input of the power supply arrangement; means for connecting an electrical load; a load current regulator, which couples the capacitor to the means for connecting the electrical load; a feedback path, which couples a means for load current detection, which is coupled to the means for connecting the electrical load, to the load current regulator; and switching means for coupling the capacitor to the input for connecting the voltage source, such that a parallel circuit of the capacitor with the voltage source is produced in a charging phase of the capacitor, and a series circuit of the capacitor with the voltage source is produced in a discharge phase of the capacitor, wherein the load current regulator comprises an inductive boost converter, wherein the power supply arrangement is configured to be operated in one out of at least a first operating mode, a second operating mode and third operating mode, wherein in the first operating mode, which is a charging mode, the power supply arrangement is configured to charge the capacitor via the means for charging the capacitor, wherein in the second operating mode, which is a discharge mode, the power supply arrangement is configured to discharge the capacitor via the load current regulator, and wherein in the third operating mode, the power supply arrangement is configured to switch on a bypass path, which directly couples the means for charging the capacitor to the means for connecting the electrical load.
