摘要： A portable power supply apparatus is provided having reduced impedance losses. The portable power supply apparatus is comprised of: a portable housing; a battery system residing in the housing; and an inverter circuit residing in the housing. The battery system generates a direct current (DC) voltage having a magnitude greater than or equal to a peak value of a desired alternating current (AC) voltage. The inverter circuit receives the DC voltage directly from the battery system, converts the DC voltage to an AC output voltage and outputs the AC output voltage to one or more outlets exposed on an exterior surface of the portable housing.

摘要： A power tool includes a brushless DC motor housed inside an upper body of the tool housing and a control unit housed inside a handle of the housing, the control unit including a micro-controller mounted on a control circuit board, a power unit electronically coupled to the micro-controller and mounted on a power circuit board arranged substantially parallel the control circuit board inside the handle, and a heat sink in thermal contact with the power unit. An input unit may be mounted directly on the control circuit board. An upper portion of the heat sink extending towards the upper body of the housing may include a tab protruding underneath a fan assembly of the motor to transfer heat from the power unit to the airflow created by the fan.

摘要： A driving tool having a driver, a power source, a sensor and a controller. The power source selectively provides an input to the driver to cause the driver to translate along an axis. The sensor senses a condition in the power source that is indicative of a level of kinetic energy of an element in the power source and generates a sensor signal in response thereto. The controller is coupled to the power source and the sensor and is responsive to the sensor signal for deactivating the power source to inhibit the power source from providing the input to the driver when the level of kinetic energy of the element in the power source is below a predetermined threshold. A method for operating a driving tool is also provided.
