Patent 12015265 was granted and assigned to Lunar Energy on June, 2024 by the United States Patent and Trademark Office.
A rapid shutdown system includes a PV (photovoltaic) generator. It further includes a DC (Direct Current)-DC converter receiving power from the PV generator and outputting power. The DC-DC converter outputs power at a high voltage state or a low voltage state. It further includes a DC bus coupled to the DC-DC converter to receive the power outputted by the DC-DC converter. The DC bus is coupled to a system comprising a load. The DC-DC converter transitions from the high voltage state to the low voltage state based at least in part on an output current of the DC-DC converter transitioning below a threshold.
