Claim:
1. An electronic circuit comprising: first and second terminals adapted to be connected across a floating source of direct current (DC) power; third and fourth terminals; first and second switches in series across the first and the second terminals, wherein a first node is formed between the first and the second switches, and wherein the first switch is between the first node and the third terminal; a first diode between the fourth terminal and a second node; and a first resonant circuit in series between the first node and a second node, wherein the electronic circuit is configured such that when the first switch is closed and the second switch is open, the first resonant circuit is connected across the first and the second terminals, and such that when the first switch is open and the second switch is closed, the third terminal, the fourth terminal, the first diode, and the first resonant circuit are in series across the first and the second terminals.
