Embodiment Construction
[0023] In order to make the purpose, technical solution and advantages of the present invention more clear and definite, the content of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only parts related to the present invention are shown in the drawings but not all content.
[0024] according to figure 1 As shown, this embodiment proposes an active RC-type DC current limiter based on dual-capacitor oscillation, including a parallel flow-through branch and a RC branch. The flow-through branch is composed of a mechanical switch MS. The resistance-capacitance branch is connected in series by the high-voltage arm capacitance branch, the low-voltage arm capacitance br...
