Abstract

The invention discloses an inversion device and a power control method thereof. The inversion device comprises a shell, a power module and a heat dissipation structure, the power module is arranged inthe shell and comprises a boosting power switch tube and an inversion power switch tube; the heat dissipation structure is arranged in the shell and comprises a draught fan, a boosting radiator and an inversion radiator; the draught fan supplies air in the first direction, and the boosting radiator and the inversion radiator are both arranged on the air outlet side of the fan and used for radiating heat for the boosting power switch tube and the inversion power switch tube respectively. The projections of the boosting radiator and the inversion radiator along the first direction are at leastpartially overlapped, and the boosting radiator is arranged closer to the fan than the inversion radiator along the air supply direction of the fan. According to the inversion device, the air supply air flow passing through the boosting radiator can still dissipate heat of the inversion radiator, and the inversion device can meet the larger heat dissipation requirement of an inversion power switchtube.

Description

technical field [0001] The invention relates to the technical field of inverters, in particular to an inverter device and a power control method thereof. Background technique [0002] An inverter device with an inverter circuit, such as a photovoltaic inverter and an uninterruptible power supply, generally includes a boost circuit and an inverter circuit coupled to each other. Both the boost circuit and the inverter circuit are equipped with power inductors and power switches (such as IGBTs). Most of the heat generated by the inverter device during operation comes from the above two devices, although there are many A heat dissipation structure is used to dissipate heat from the above-mentioned devices, but it is still difficult to solve the defects of low heat dissipation capacity and heat dissipation efficiency of the existing inverter device. Contents of the invention [0003] The object of the present invention is to overcome at least one defect or problem existing in ...
