Claim:
1. A circuit comprising: a first switch configured to perform a first switching function when the circuit is in a first operation mode and configured as a first diode when the circuit is in a second operation mode; a second switch configured as a second diode when the circuit is in the first operation mode and configured to perform a second switching function when the circuit is in the second operation mode; a hold-up capacitor coupled in series with the first switch and having two terminals, the first terminal coupled to a first contact of the first switch and the second terminal coupled to a first contact of the second switch; wherein the hold-up capacitor is coupled to charge in the first operation mode based, at least in part, on the first switching function; wherein the hold-up capacitor is coupled to discharge in the second operation mode based, at least in part, on the second switching function; a single inductor having a first terminal that is connected to a power bus line of a bus and a second terminal that is connected to both a second contact of the first switch and a second contact of the second switch; wherein the single inductor and the capacitor are coupled in series between the first bus line and a second bus line of the bus.
