AI Technical Summary
Technical Problem
In some countries or regions with weak infrastructure, when a phase of the power grid is missing, the existing power supply circuits have poor flexibility and/or low stability, making it impossible to supply power to the load normally.
Method used
In the power supply circuit, each channel interface is equipped with an independent switch. The control unit detects the power grid status and flexibly selects the normal channel for power supply or switches to the backup power source, such as a generator, to ensure stable power supply to the load.
Benefits of technology
It enables stable power supply to the load and flexible charging of energy storage devices in the event of a phase loss in the power grid, thereby improving the flexibility and stability of the power supply circuit.
