ABSTRACT:
For use in a boost converter having first and second boost switches coupled in parallel, a snubber for, and method of, improving current sharing between the first and second boost switches. In one embodiment, the snubber includes: (1) first and second snubber inductors, series-coupled with the first and second boost switches, respectively, that limit a flow rate of the electrical current in the first and second switches, respectively, as a function of a rate of the flow and (2) a conductive path, including a first zener diode coupled to a first node between the first snubber inductor and the first boost switch and a second zener diode coupled to a second node between the second snubber inductor and the second boost switch, that conducts a turn-off energy of said first and second boost switches from the first and second nodes toward an output of the boost converter.
