Abstract
The present disclosure relates to power management systems utilizing a high-frequency low voltage pre-charge. A power management system may comprise a low voltage power source, a power supply assembly connected to the low voltage power source, and a power module comprising a plurality of arrays. Each array may comprise a plurality of electrically isolated stacks connected through a synchronous common coupling. Each electrically isolated stack may comprise a plurality of stages, a multi-winding secondary, a pre-charge circuit connected to at least one of the plurality of stages, and a plurality of multi-winding isolated power supplies. Each multi-winding isolated power supply may be connected to one of the plurality of stages. The power supply assembly may be configured to supply charging current from the low voltage power source to at least one of the plurality of electrically isolated stacks.
