1. A snubber for a pulsed DC power supply system, the snubber comprising:
an input coupled to a DC power supply;
an output coupled to a switching circuit, the switching circuit configured to provide pulsed DC power to a load;
a low-level connection of the DC power supply;
a first inductive element coupled between a first node and a second node;
a second inductive element coupled between the first node and a third node, the third node coupled to the output;
a capacitive element coupled between the first node and a fourth node;
a first switch coupled between the third and fourth nodes;
a second switch coupled between the second and fourth nodes; and
a third switch coupled between the second node and the low-level connection of the DC power supply.
