1. A control method of an optical storage converter, comprising:
obtaining a voltage measurement and a current measurement of a universal interface of the optical storage converter in the case where an apparatus is accessed to the universal interface, to determine whether the apparatus accessed to the universal interface is a photovoltaic system or an energy storage system; and
adjusting an internal circuit of the optical storage converter correspondingly in the case where the accessed apparatus is the photovoltaic system or the energy storage system, wherein one universal interface corresponds to one DC to DC converter circuit, the DC to DC converter circuit comprises a first module and a second switch tube module connected in series, the first switch tube module comprises a first switch tube and a first freewheeling diode, the second switch tube module comprises a second switch tube and a second freewheeling diode, a first port of the first switch tube module is connected to a first port of a capacitor, a second port of the first switch tube module is connected to a first port of the second switch tube module, a second port of the second switch tube module is connected to a second port of the capacitor, the second port of the first switch tube module is connected to a first port of the universal interface through an inductor, and the second port of the second switch tube module is connected to a second port of the universal interface.
