Claim 9:
10. A power converter, including:
(a) a first switch having a control input for setting the first switch to an open state or to a closed state;
(b) a second switch having a control input for setting the first switch to an open state or to a closed state;
(c) a set of one or more switches coupled in series, the set being coupled in series between the first switch and the second switch; and
(d) a first auxiliary protection circuit coupled between the control input of the first switch and a source of a subsequent adjacent switch within the set of one or more switches, and a second auxiliary protection circuit coupled between the control input of the second switch and a drain of a preceding adjacent switch within the set of one or more FET power switches;
wherein the first switch and the second switch are set to the closed state during normal operation of the power converter, and at least one of the first switch and the second switch is set to the open state in response to one or more events.
