Abstract

The invention discloses an inverter device and a power control method thereof. The inverter device includes: a casing, a power module and a heat dissipation structure; the power module is arranged in the casing and includes a boost power switch tube and an inverter Variable power switch tube; the heat dissipation structure is arranged in the housing and includes a fan, a boost radiator and an inverter radiator; the fan blows air along the first direction, and the boost radiator and inverter radiator Both are arranged on the air outlet side of the fan and are used to dissipate heat for the boost power switch tube and the inverter power switch tube respectively; the step-up radiator and the inverter radiator along the first direction The projections are at least partially overlapped, and along the blowing direction of the fan, the boost radiator is arranged closer to the fan than the boost radiator. The inverter device of the present invention can still dissipate heat to the inverter radiator through the air supply airflow passing through the booster radiator, and can adapt to the greater heat dissipation demand of the inverter power switch tube.

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 ...
