A diode (D2) is connected between the second coil (L2) and the power supply side of the load (12) for transferring the received energy back to the power supply side of the load (12).

The solar dual-supply circuit can realize solar cell supply and dual supply, which is not only environmentally friendly and energy-saving but can also ensure the supply demand of the load.

Stabilization of the d.c. supply current of the user"s line.

Therein the power-free status of the power supply output of the system is confirmed visually.
