Dynamic voltage control for power source communication
A recently granted patent (Publication Number: US11916378B2) discloses a method for operating a power source, specifically a solid oxide fuel cell (SOFC) system, to efficiently provide power to a load while ensuring the system operates within specified power thresholds. The method involves adjusting the output voltage of the power source on a power bus to communicate with a device, such as an inverter, and the load, to track and meet the power demand of the load. By monitoring the power demand and potential threshold exceedances, the system can effectively manage power output without compromising performance.
Furthermore, the patent details a strategy for directing excess output power from the SOFC system to an additional load when the power demand from the primary load drops below a minimum desired operating power level. This approach helps maintain the efficiency of the SOFC system and ensures optimal performance even during fluctuating power demands. Additionally, the method includes provisions for redirecting excess power back to the primary load when demand increases, without relying on auxiliary power sources, thereby enhancing overall system efficiency and reliability. Overall, the patented method offers a comprehensive and efficient approach to power management in SOFC systems, ensuring reliable power supply while optimizing system performance based on varying load demands.
