Publication number: 20200288588Abstract: A power supply apparatus is provided including a housing, at least one battery receptacle for receiving at least one removable battery pack, an inverter that converts a direct-current (DC) signal from the at least one battery pack to an alternating-current (AC) signal, and a controller that applies a pulse-width modulation (PWM) signal to the inverter to shape the AC signal with a lower harmonic distortion relative to a square wave. For each full cycle of the AC signal, the controller sets the duty cycle to approximately 100% within a first period corresponding to a peak area of the AC signal, to less than approximately 100% but greater than approximately 0% within a second period in which the AC signal transitions from the peak to a zero-cross following the first period, and to 0% within a third period corresponding to the zero-cross of the AC signal following the second period.Type: ApplicationFiled: May 27, 2020Publication date: September 10, 2020Inventors: Snehal S. CHOKSI, Geoffrey S. HOWARD, Daniel L. SCHWARZ, Thomas C. KOHLER, Keith HOPWOOD, Richard A. SY, Chun-Te CHIN, Jiunping HUANG, Minghuang HUNG

Patent number: 10674618Abstract: The present invention is directed to a portable power supply system. The system is capable of converting DC power from one or more removable, rechargeable battery packs to AC power for corded power tools and appliance. The system is also capable of receiving AC power from an AC power supply and converting the AC power to DC power and using the DC power to charge the removable, rechargeable battery packs. The system includes a heat sink to assist in dissipating heat generated by various electronic components in the system. The heat sink also serves as a structural element to provide structural support to a housing of the system.Type: GrantFiled: September 4, 2018Date of Patent: June 2, 2020Assignee: BLACK & DECKER INC.Inventors: Snehal S. Choksi, Geoffrey S. Howard, Daniel L. Schwarz, Thomas C. Kohler, Keith Hopwood, Richard A. Sy, Chun-Te Chin, Jiunping Huang, Minghuang Hung
