1. A system, comprising:
a first bridge circuit comprising a first plurality of switches, the first plurality of switches receiving a first voltage and providing a second voltage based on at least the first voltage;
at least one transformer, the at least one transformer providing a third voltage based on the second voltage;
a second bridge circuit comprising a second plurality of switches, the second plurality of switches providing a fourth voltage based on at least the third voltage; and
at least one controller programmed to selectively activate at least one of the first plurality of switches, the at least one of the first plurality of switches, when activated, providing the second voltage and selectively activating at least one of the second plurality of switches, when activated, providing the fourth voltage based on a predetermined modulation scheme, wherein the predetermined modulation scheme is based on at least a number of turns of the at least one transformer and a difference between a first rise time delay associated with a first switch of the second plurality of switches and a second rise time delay associated with a second switch of the second plurality of switches.
