  • Power converters with wide bandgap semiconductors
    Patent number: 11923716
    Abstract: Power converting devices (100) for power tools. One embodiment provides a power converter device (100) including a power source (200), a power converter (210) coupled to the power source (200), and an electronic processor (220) coupled to the power converter (210) to control the operation of the power converter (210). The power converter (210) is configured to receive an input power in one form or at a first voltage from the power source and convert the input power to an output power in another form or at a second voltage. The power converter (210) includes at least one wide bandgap field effect transistor controlled by the electronic processor (220) to convert the input power to output power.

  • PORTABLE POWER SUPPLY
    Publication number: 20220200303
    Abstract: A portable power supply including an internal power source, an AC output, a DC output, and an input unit configured to receive power from a first external source. The portable power supply further includes a first power conversion unit configured to convert the power received from the first external source to a first DC power used for charging the internal power source, an AC power conversion unit configured to convert power output by the internal power source to an AC power used for powering a first peripheral device connected to the AC output, and a DC power conversion unit configured to convert power output by the internal power source to a second DC power used for powering a second peripheral device connected to the DC output.
