Embodiment Construction
[0024] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0025] The step-down chopper circuit provided by the embodiment of the present invention has a first-stage step-down unit and a second-stage step-down unit. Compared with step-down, the input voltage can be greatly reduced. Therefore, under the premise that the output voltage remains unchanged, the step-down chopper circuit can greatly increase the voltage input range compared with the first-stage step-down circuit.
[0026] figure 1 The structure of the step-down chopper circuit provided by the embodiment of the present invention is shown, and for the convenience of description, only the parts re...
