Abstract

The embodiment of the invention discloses a generator charging circuit, a generator and a generator starting method. The generator charging circuit comprises a direct current input end, a controller and at least two charging circuits, and each charging circuit comprises a voltage regulating module, a selector switch and a charging interface which are connected in sequence; and the selector switch comprises an input end, a first output end and a plurality of second output ends, the input end of the selector switch of each charging circuit is connected with the voltage regulating module, the first output end of the selector switch is connected with the charging interface of the charging circuit, and the plurality of second output ends of the selector switch are connected with the charging interfaces of other charging circuits. Before the generator is started, the controller enables the input end of the selector switch in the charging circuit without battery access to be connected to the second output end, the voltage regulating module of the charging circuit without battery access is clamped by batteries of other charging circuits, and the voltage difference of electronic devices of the voltage regulating module is within a voltage withstanding range. And the electronic device is prevented from being damaged by an overlarge voltage at the starting moment of the generator.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of generator charging, and in particular to a generator charging circuit, a generator and a generator starting method. Background technique [0002] Electric-driven drones use lithium batteries as power sources. Since it is inconvenient for drones to obtain 220V AC mains power when working outdoors, generators are usually used to charge lithium batteries. [0003] UAVs are usually equipped with multiple lithium batteries. In order to meet the charging needs, the generator charging circuit is usually equipped with multiple charging circuit outputs to charge multiple lithium batteries at the same time. Such as figure 1 The charging circuit of the generator shown is provided with two charging circuits, which can charge two lithium batteries at the same time, each charging circuit includes an electronic switch, the input end of each charging circuit is connected with the output end of ...
