Early challenges in distributed power generation control system adoption—such as weak power signal capture, electromagnetic interference (EMI), and poor electrical safety isolation in distributed grid scenarios—have been overcome by specialized PCB assembly technologies, particularly high-efficiency rigid-flex PCBs and high-precision surface mount technology (SMT).
These innovations effectively enhance the sensitivity of analog front-ends for capturing faint power generation signals (voltage, current, frequency, and power output), while integrating EMI shielding layers to eliminate interference from grid equipment and distributed generation units (PV, wind, small hydropower).
