Synopsis

Patent US 11,032,826 B2 describes a multi-port power converter system and a method for operating it, designed for applications requiring bidirectional power flow among multiple direct current (DC) energy sources and loads. This invention addresses the challenges of efficiently managing power in complex systems that integrate diverse power sources (such as renewable energy, batteries, and conventional DC supplies) with various loads, ensuring stable and optimized power distribution.
A key novel aspect of this patent is its architecture, which employs multiple individual converter modules, each capable of independently handling bidirectional power flow between a port and a common bus. These modules are designed to manage power flow across different voltage levels and to facilitate power sharing among connected sources and loads. Each module is equipped with a bidirectional switch, allowing power to flow in either direction, enabling functionalities like charging batteries, supplying loads from a source, or drawing power from a load (e.g., regenerative braking). The system's controller can manage the power flow dynamically, reacting to changes in source availability, load demand, and battery state of charge. This modular and bidirectional design offers enhanced flexibility, reliability, and efficiency compared to traditional centralized or unidirectional power conversion systems.
The commercial potential of this invention is significant across various sectors that are increasingly relying on distributed power generation, energy storage, and DC microgrids. The ability to seamlessly integrate and manage multiple DC power sources and loads makes it highly adaptable for complex energy ecosystems.

Possible applications include:
Electric Vehicles and Charging Infrastructure: Enabling efficient bidirectional power flow for electric vehicle charging stations, allowing vehicles to not only draw power but also return energy to the grid (vehicle-to-grid, V2G), enhancing grid stability and supporting renewable integration. It could also optimize power management within the vehicle itself, integrating batteries, fuel cells, and regenerative braking.
Renewable Energy Systems: Facilitating the integration of solar photovoltaic (PV) arrays, wind turbines, and energy storage systems (batteries) into DC microgrids. This system can efficiently manage power fluctuations from intermittent renewable sources, ensuring a stable power supply to loads.
Data Centers: Improving the energy efficiency and reliability of data centers by enabling native DC power distribution, reducing conversion losses associated with multiple AC-DC conversions. It can also support seamless integration of battery backup systems and renewable power sources.
Telecommunications and Remote Grids: Providing reliable power management for off-grid or remote telecommunication sites and community microgrids, which often rely on a mix of renewable energy, batteries, and diesel generators.
Smart Homes and Buildings: Optimizing energy usage and storage in residential and commercial buildings equipped with solar panels, battery storage, and smart appliances, allowing for demand-side management and energy cost reduction.
Industrial Automation: Powering industrial machinery and robotics with efficient DC power, potentially integrating regenerative capabilities to recover energy during operation.

This patent offers a versatile and robust solution for modern power management, providing a pathway to more efficient, flexible, and resilient electrical systems that can effectively integrate diverse energy sources and loads.
