Abstract
Disclosed are various embodiments of resonant power management of a mobile device. In one embodiment, a mobile device including a power management unit (PMU) including a resonant inverter, a plurality of AC/DC converters, and an AC bus configured to route the AC power from the resonant inverter to the plurality of AC/DC converters. The resonant inverter converts DC power from a power source to AC power that is converted to DC power by the AC/DC converters and supplied to loads of the mobile device. In another embodiment, a method for power management of a mobile device includes monitoring, by a PMU of the mobile device, an operating mode of the mobile device and adjusting an output frequency of a resonant inverter of an AC power distribution network of the PMU in response to a change in the operating mode of the mobile device.
