Abstract: An interface circuit, a string, and a system that are applied to power line communication, to lower device specifications, includes: an inverter, an optimizer group, a capacitor, a magnetic ring, power lines, and a signal line. An optimizer in the optimizer group is configured to adjust a size of a direct current output by a photovoltaic module connected to the optimizer. Two ends of the signal line passing through the magnetic ring are connected to the inverter. Two ends of a power line passing through the magnetic ring are respectively connected to the capacitor and the optimizer group. By using the foregoing interface circuit, a high voltage of a direct current output by the optimizer group is prevented from being introduced into the inverter, thereby reducing a specification requirement of a device such as a capacitor.

Abstract: This application relates to the field of electronic device technologies, and provides an electronic component with an enclosure frame, a circuit board with an electronic component, and an electronic device, to effectively protect the circuit board from being corroded, thereby prolonging a service life of the electronic device. This application is applied to a charging pile for charging a new energy electric vehicle. An electronic component with an enclosure frame includes an enclosure frame and an electronic component. The enclosure frame defines a cavity that is closed or that has one open end; when the electronic component with an enclosure frame is connected to a circuit board, the enclosure frame and the circuit board can define a cavity that is closed or that has one open end.
