A photovoltaic (PV) shutdown system for a PV power generation system includes a mid-circuit interrupter (MCI) controller and at least one MCI with two terminals. The two terminals of the at least one MCI are arranged for connection with the MCI controller, a maximum power point tracking (MPPT) system, and a PV string. The PV string includes PV modules connected in series. The MCI controller is arranged to turn on the at least one MCI by providing supply power and turn off the at least one MCI by terminating the supply power.

A thin film inductor is disclosed, which includes a thin film magnetic core. The thin film magnetic core includes at least one magnetic thin film. In each magnetic thin film, at least one type-1 gap is provided. A length direction of the type-1 gap is parallel to a direction of hard magnetization of the magnetic thin film. If the thin film magnetic core comprises at least two magnetic thin films, the at least two magnetic thin films are laminated and overlap each other. A sum of widths of all type-1 gaps in each magnetic thin film is the same.
