High-power wireless transmission and conversion
Systems and methods provide wireless power to an Information Handling System (IHS). A multimode wireless power transmission unit supports USB-PD (Universal Serial Bus Power Delivery) power transmissions and also supports a high-power transmission of a voltage greater than USB-PD transmission voltages. The IHS detects the wireless coupling of the wireless power transmission unit. As part of this coupling, the IHS determines whether the wireless power transmission unit supports high-power transmissions. A wireless power transfer is negotiated and a power circuit of the IHS is configured for converting the negotiated high-power transmission to an input utilized by the IHS. Embodiments utilize a power circuit that provides efficient conversion of power transmissions of up to 60 volts. This same power circuit also provides efficient conversion of power transmissions of up to 60 volts by a multimode USB-C power adapter.
