Latest Patents
One of his notable patents is a portable power supply apparatus that includes a housing, at least one battery receptacle for receiving removable battery packs, an inverter for converting direct-current (DC) signals to alternating-current (AC) signals, and a controller that applies a pulse-width modulation (PWM) signal to shape the AC signal. This innovation aims to reduce harmonic distortion relative to a square wave. The controller sets the duty cycle to approximately 100% during the peak area of the AC signal and adjusts it during the transition to zero-crossing.
Another significant invention is a portable power supply system capable of converting DC power from rechargeable battery packs to AC power for corded tools and appliances. This system can also receive AC power and convert it to DC for charging the battery packs. It features a heat sink that dissipates heat generated by electronic components while providing structural support to the housing.
