Abstract: Power tools that include a housing, a motor supported by the housing, a battery pack interface configured to receive a battery pack that includes a plurality of battery cells, an inverter positioned between and electrically connected to the battery pack interface and the motor, a gate driver connected to the inverter and configured to control a current in the inverter, a controller configured to control the gate driver, and a short circuit detection circuit. The short circuit detection circuit is configured to monitor the current in the inverter, compare the current in the inverter to a short circuit threshold, and control a switch of the short circuit detection circuit to disable the gate driver when the current in the inverter is greater than or equal to the short circuit threshold.

Abstract: A portable power supply including an alternating current (“AC) power input interface, an AC power output interface, and a battery core. The power supply further includes at least one switch. The at least one switch is electrically connected between the AC power input interface and the battery core. The power supply also includes a controller configured to control the at least one switch to selectively provide an AC power output to the AC power output interface based on power received from either the AC power input interface or the battery core.
