Abstract
A system includes a boost circuit, a capacitive circuit, and a converter circuit. The boost circuit receives a DC signal at a first DC voltage and generates an intermediate AC signal at a first AC voltage based on the DC signal. The capacitive circuit receives the intermediate AC signal at the first AC voltage and generates an isolated AC signal at the first AC voltage based on the intermediate AC signal at the first AC voltage. The converter circuit receives the isolated AC signal at the first AC voltage; generates a first isolated DC signal at a second DC voltage based on the isolated AC signal at the first AC voltage; and generates a second isolated DC signal at a third DC voltage based on the first isolated DC signal at the second DC voltage. The third DC voltage may be less than the second DC voltage.
