Self-Synchronizing Power Modules for Scalable Microgrids
Here’s PatSnap Eureka !
Summary
Problems
Current automatic synchronization systems for AC power sources in power grids are complex, costly, and limited in expandability, requiring manual or automatic tuning and master-slave control topologies, which are not suitable for hot-plugging and are economically inefficient, especially in small-scale microgrids.
Innovation solutions
The development of self-synchronizing electrical components and systems that can autonomously synchronize AC signals using nonlinear and chaotic circuits, eliminating the need for microprocessors, frequency-locked loops, and phase-locked loops, allowing for modular and scalable power systems that can hot-swap power modules without synchronization.

Specific contradictions:
General conflict description:
Principle concept:
If traditional automatic synchronization systems with sensors, processors, and control systems are used, then synchronization can be achieved, but device complexity and cost increase significantly
Why choose this principle:
The patent extracts the synchronization control logic from external processors and control systems, embedding it directly into the power module's oscillator circuit. This eliminates the need for separate sensors, microprocessors, and control software, reducing device complexity while maintaining synchronization reliability through the module's inherent self-synchronizing capability
Principle concept:
If traditional automatic synchronization systems with sensors, processors, and control systems are used, then synchronization can be achieved, but device complexity and cost increase significantly
Why choose this principle:
The power module achieves self-synchronization through its oscillator circuit that automatically adjusts to match the frequency and phase of the AC source without requiring external control systems. The module serves its own synchronization needs through intrinsic circuit behavior rather than external control, eliminating complex control infrastructure

Abstract
The present disclosure is directed to self-synchronizing devices that can connect and self-synchronizes voltage, frequency and phase of two or more power sources. The disclosed embodiments enable a modular power system to serve as the primary or secondary source of power for applications requiring loads from a few kilowatts (kW) to the scale of megawatts (MW). The modular system is generalized to use either a single or multiple power generation sources at once, with the ability to connect and self-synchronize voltage, frequency, and phase of a variety of different types of power sources. Power control systems designed to function with self-synchronizing technology enable a modular power system to satisfy a wide variety of needs, simplifying the existing method of achieving synchronization and enabling new features of resiliency and expandability. The self-synchronization can be implemented into a wide variety of electronics including but not limited to inverters and generator controllers.
