The utility model relates to a main circuit structure of an inverter stacking busbar. The main circuit structure comprises a high-voltage stacking busbar, a heat radiator, a power module and an AC output bus, wherein the high-voltage stacking busbar is arranged on a module; the power module is arranged on the heat radiator; a fan is arranged under the heat radiator; the high-voltage stacking busbar is provided with three phases, and the DC sides of the three phases are respectively communicated through a positive bus and a negative bus; and the AC sides of the three-phase high-voltage stacking busbar are mutually independent. The main circuit structure can endure higher voltage and stronger current, and has simple structure and easy disassembly and maintenance.
