Abstract

This invention provides a miniature general-purpose electrical control device and method, including a power adapter module, a PLC programming control unit, a central coordination controller, and an integrated control module. The invention acquires input power signals, identifies their type and amplitude range, and generates electrical state identifiers. Based on these identifiers, it selects the corresponding rectifier topology, converting the input power into a stable intermediate DC bus voltage, forming a reconfigurable DC energy pool. It acquires multi-channel load state data through miniature sensor nodes, generating a multi-dimensional load feature vector. Using an improved fuzzy PID coordination controller, it integrates load characteristics with a preset channel priority strategy, calculates energy demand weights, and generates a dynamic power allocation matrix. Based on this matrix, it adjusts the operating mode and power flow of the bidirectional DC / DC converter. This invention significantly improves power adaptability and energy utilization in multi-input, multi-output power supply scenarios, effectively addressing complex operating conditions such as grid fluctuations and uneven load distribution.
