The invention relates to a power supply device and a power supply system, the power supply device comprises a photovoltaic converter, a fan converter, a battery converter, an off-grid inverter and a DC bus, the photovoltaic converter, the fan converter, the battery converter and the off-grid inverter are all connected with the DC bus, the photovoltaic converter is used for accessing a photovoltaic module, the fan converter is used for accessing a wind driven generator, and the off-grid inverter is connected with the DC bus. The battery converter is used for being connected with a battery pack, the off-grid inverter is used for inverting direct current from the direct current bus into alternating current and then outputting the alternating current, and the direct current bus is further used for outputting the direct current. By adopting a direct current bus coupling technology, photovoltaic power generation and fan power generation are directly introduced into a direct current bus, the utilization rate of photovoltaic power generation and fan power generation is improved, available electric energy of a system is increased, the direct current bus is accessed through a battery converter, access of different battery packs can be supported, and the direct current bus can output direct current and alternating current. The device can be used by direct-current and alternating-current electric appliances, and is wide in application scene and convenient to use.
Description
technical field [0001] The present application relates to the technical field of microgrid power supply, in particular to a power supply device and a power supply system. Background technique [0002] With the development of new energy power generation technology, the application range of distributed photovoltaic power generation and distributed wind power generation is becoming wider and wider, with good development prospects. Electrochemical energy storage technology has developed by leaps and bounds in recent years and has been widely used in many fields. [0003] In recent years, low-voltage DC household appliances have received more and more attention from manufacturers. The application of low-voltage DC has higher safety. For distributed new energy generation, direct conversion to low-voltage DC can also improve the conversion efficiency of the system. . Traditional microgrid solutions generally only have AC output interfaces, and most systems are directly connected ...
