Claim 0:
1. A bias supply to apply a periodic voltage comprising:
an output node;
a return node;
a switch;
a first inductor coupled between a first node of the switch and the output node;
a first node of a second inductor coupled to one of the output node or the first node of the switch;
a voltage source coupled between a second node of the switch and a second node of the second inductor;
a connection between the return node and one of the second node of the switch and the second node of the second inductor; and
a controller configured to cause an application of the periodic voltage between the output node and the return node by repeatedly closing the switch for a time just long enough for current through the switch to complete a full cycle from zero to a peak value, back to zero, to a peak value in an opposite direction and back to zero.
