Claim Text:
1. A rapid-transition switch-mode direct-current to direct-current (DC-DC) converter for delivering electrical power to a load, comprising: an output filter including an inductor and a capacitor; a first switch having a first control terminal configured to receive a first ON/OFF switch control signal that causes said first switch to alternately and repeatedly couple and decouple the inductor of said output filter to and from a DC input voltage as power is being delivered to the load and causes said first switch to remain OFF upon and as power to the load is being removed; and a second switch coupled in series with said capacitor, said second switch having a second control terminal configured to receive a second ON/OFF switch control signal that causes said second switch to remain ON during times power is being delivered to the load and causes said second switch to turn OFF, electrically isolate said capacitor, and prevent said capacitor from discharging through the load immediately upon and as power delivery to the load is being removed.
