The invention discloses a direct-current electric energy generation circuit for new energy application. When an input alternating-current voltage is in a high-voltage range, an output voltage of a rectifying circuit is reduced to obtain an output voltage of the direct-current electric energy generation circuit; and when the input alternating-current voltage is in a low-voltage range, the output voltage of the rectifying circuit is directly used as the output voltage of the direct-current electric energy generation circuit, so that the output voltage of the AC-DC voltage is close to each otherwhen the input alternating-current voltage is in the high-voltage range and the low-voltage range. According to the direct-current electric energy generation circuit, the output voltage range of the direct-current electric energy generation circuit is reduced, the optimization and selection of post-stage power devices are facilitated, and the direct-current electric energy generation circuit has obvious advantages especia
