Embodiment Construction

[0051] It should be noted that components in the various figures may be shown exaggerated for the purpose of illustration and are not necessarily true to scale. In the various figures, identical or functionally identical components are assigned the same reference symbols.

[0052] In the present invention, unless otherwise specified, "arranged on", "arranged on" and "arranged on" do not exclude the presence of intermediates between the two. In addition, "arranged on or above" only means the relative positional relationship between two parts, and under certain circumstances, such as after the product direction is reversed, it can also be converted to "arranged under or below", and vice versa Of course.

[0053] In the present invention, each embodiment is only intended to illustrate the solutions of the present invention, and should not be construed as limiting.

[0054] In the present invention, unless otherwise specified, the quantifiers "a" and "an" do not exclude the scen...

Abstract

The present invention relates to a backup power supply comprising: a first sub-power supply configured to provide alternating current power wherein the first sub-power supply is connected to an input of an AC / DC converter; the AC / DC converter is configured to convert alternating current electric energy into direct current electric energy, and the output end of the AC / DC converter is connected to the output end of the standby power supply; and the second sub-power supply is configured to provide direct-current electric energy, and the second sub-power supply is connected to the output end of the standby power supply. In addition, the invention also relates to an operation method of the standby power supply. According to the invention, a stand-by power supply scheme which is high in reliability and can adapt to the power utilization requirements of loads with relatively large power requirement changes, such as a fan, can be provided.

Description

technical field [0001] The present invention generally relates to the field of wind power generators, and more specifically relates to a backup power supply and an operating method thereof. Furthermore, the invention also relates to a wind generator with such a backup power source. Background technique [0002] In recent years, with the increasing emphasis on the environment in various countries, the field of clean energy has shown a trend of rapid development. As a new type of energy, clean energy has the advantages of wide distribution, renewable, and less environmental pollution compared with traditional fossil fuels. As a representative of clean energy, the application of wind power generators is increasing day by day. In addition, due to the restrictions on the movement of people due to force majeure such as the new crown epidemic in recent years, the advantages of power generation devices such as wind turbines that can operate for a long time without personnel operat...
