摘要： This application discloses a method, an apparatus, and a system for obtaining electronic layout applied to photovoltaic array in the field of equipment installation management. According to the method, the electronic device identifies each first area in a target picture to obtain position information and a module identifier of at least one photovoltaic module in each first area, and may directly obtain an electronic layout based on the position information and the module identifier of each photovoltaic module. In this way, a product identifier of each converter does not need to be manually obtained, and a photovoltaic module does not need to be manually added to the electronic layout. This reduces labor time consumption and improves efficiency of obtaining the electronic layout.

摘要： This application describes a totem-pole power factor correction circuit and a power supply module. A detection circuit of the totem-pole power factor correction circuit can detect a current between a power transistor and a bridge arm middle point, and determine a current value when an inductor is charged. When a control circuit controls a drive circuit to drive the power transistor to be turned on, in response to a value of a current flowing through the inductor being greater than a first predetermined value, the drive circuit can drive, in time based on a detection result of the detection circuit, the power transistor to be turned off, to protect the power transistor.

摘要： An inverter includes a direct current-alternating current (DC-AC) conversion circuit and a filter circuit, where the filter circuit is connected to an alternating current side of the DC-AC conversion circuit. The filter circuit includes an integrated inductor. The integrated inductor includes a common mode magnetic core, a differential mode magnetic core, and at least two windings. The differential mode magnetic core includes a second magnetic core and a third magnetic core. The common mode magnetic core, the second magnetic core, and the third magnetic core are stacked in sequence. Each winding is located between the third magnetic core and the second magnetic core and is wound on the common mode magnetic core and the second magnetic core. The at least two windings are spaced by the third magnetic core. Set as such, a product volume can be reduced while common mode interference and differential mode interference are suppressed.

摘要： This application describes examples of a photovoltaic energy storage system including an inverter and an energy storage device. In one example, an input end of the inverter is connected to a direct current bus. An output end of the inverter is connected to an alternating current power grid. The energy storage device is connected to the direct current bus. The inverter is configured to send high-voltage ride-through information to the energy storage device when a high-voltage ride-through occurs in the alternating current power grid. The energy storage device is configured to: when the high-voltage ride-through information is received, adjust an output voltage reference value to maintain a discharging working state if the energy storage device is in the discharging working state, or adjust a charging power reference value to maintain a charging working state if the energy storage device is in the charging working state.
