Problems solved by technology

The choke coil coupling energy storage device has a simple structure and can distribute short-term power, but its voltage is unbalanced, which may easily cause "mutual impact" between the supercapacitor and the chemical power supply. When the load power changes, the rapid response capability is insufficient.
