Abstract
A system includes an inductance, a sensing circuit, a filter circuit, and a switch. The inductance includes a first terminal connected to (i) an output of a power supply supplying a DC voltage and (ii) a load, and a second terminal connected to a node. The sensing circuit is configured to sense voltage at the node. The filter circuit is configured to filter the voltage at the node, and output a filtered voltage. The switch is configured to communicate with the node, and control current through the load based on the filtered voltage.
