    Abstract: A dual-voltage charging station system for an alternating current (“AC”) power supply and a mobile platform having a charging port includes a charge coupler, an AC-to-DC conversion stage, a cable, and a controller. The charge coupler has AC pins and direct current (“DC”) pins configured to engage with respective AC and DC receptacles of the charging port. The conversion stage is connected to the charge coupler and the AC power supply, converts the supply voltage to a DC charging voltage, and relays an appropriate AC or DC accessory voltage. The cable connects to the charge coupler such that the AC pins receive the accessory voltage and the DC pins receive the DC charging voltage. The controller simultaneously delivers the accessory voltage and the DC voltage to the mobile platform via the AC pins and the DC pins, respectively.

    Abstract: An AC electronic solid-state switch includes an electrically insulating and thermally conductive layer, a first electrically conductive trace, a second electrically conductive trace, and a plurality of semiconductor dies each electrically connected to the first electrically conductive trace and the second electrically conductive trace. Each of the plurality of semiconductor dies forms a MOSFET, IGBT or other types of electronically controllable switch. The AC electronic solid-state switch further includes a common drain conductor that is electrically connected to each drain terminal of the plurality of semiconductor dies. The AC electronic solid-state switch is configured to block between 650 volts and 1700 volts in the off-state in a first direction and a second direction, the second direction being opposite the first direction, and the AC electronic solid-state switch is configured to carry at least 500 A continuously in the on-state with a voltage drop of less than 2V.
