Patent number: 12089351Abstract: 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: GrantFiled: May 27, 2020Date of Patent: September 10, 2024Assignee: BLACK & DECKER INC.Inventors: Snehal S.
