Abstract
A high-voltage DC floating system includes a source, a power rail, a power bus, a load, and a pre-charge circuit. The power bus includes a positive bus portion and a negative bus portion. The pre-charge circuit includes a first pre-charge circuit portion that is configured to equalize a voltage across the positive power supply switch between the source and a Y-capacitance of the load and a second pre-charge circuit portion that defines a switched path to ground that is configured to equalize a voltage associated with a Y-capacitance of the negative power rail.
