Inventor: SHUI WEI
IPC: H02J3/38
Filed: 2020-05-25
Abstract: Embodiments of the present application disclose an interface circuit, a string, and a system applicable to power line communication (PLC), and used to reduce device specification requirements such as safety specifications and tolerance values, and reduce design difficulty. The system comprises: an inverter, an optimizer group, a capacitor, a magnetic ring, a power line, and a signal line. An optimizer in the optimizer group is used to adjust a direct current outputted by a photovoltaic assembly connected to the optimizer. Two ends of the signal line passing through the interior of the magnetic ring are connected to the inverter. Two ends of the power line passing through the interior of the magnetic ring are respectively connected to the capacitor and the optimizer group. The interface circuit consisting of the signal line, the magnetic ring, the power line, and the capacitor is used to transmit a PLC signal. The interface circuit prevents a high voltage of a direct current outputted by the optimizer group from being introduced into the inverter, thereby reducing specification requirements of devices such as a capacitor, and reducing design difficulty.
