1. A dual output energy conversion device, wherein the dual output energy conversion device comprises:
a first energy storage module, a first combined series bridge arm module, a capacitive energy storage module, and a second combined series bridge arm module;
wherein the first energy storage module, the first combined series bridge arm module, the capacitive energy storage module, and the second combined series bridge arm module are connected in sequence;
wherein the first combined series bridge arm module comprises a first main switching tube bridge arm unit and a first auxiliary tube bridge arm unit connected in series;
wherein the second combined series bridge arm module comprises a second main switching tube bridge arm unit and a second auxiliary tube bridge arm unit connected in series;
wherein the first main switching tube bridge arm unit and the second main switching tube bridge arm unit form a first conversion output circuit, outputting energy of the first energy storage module and/or the capacitive energy storage module to a first subsequent load; and
wherein the first auxiliary tube bridge arm unit and the second auxiliary tube bridge arm unit form a second conversion output circuit, outputting energy of the first energy storage module and/or the capacitive energy storage module to a second subsequent load.
