Inverter device

An inverter device, comprising:

• an inverter circuit comprising a circuit substrate, a switching device, and a through-hole device, the switching device comprises pins and a body, the through-hole device comprises pins and a body, and the pins of the switching device and the pins of the through-hole device are mounted on a same surface of the circuit substrate;
• a housing, configured to form a first cavity, wherein the inverter circuit is accommodated in the first cavity, a surface, facing the circuit substrate, of a bottom plate of the housing comprises a supporting component, the body of the switching device is carried on the supporting component, and the supporting component is made of a thermally conductive material;
• and
• a first component;
• located between the body of the switching device and the supporting component, wherein the first component is made of a thermally conductive insulation material;
• and
• a second component;
• configured to connect the body of the switching device to the supporting component, wherein
• the inverter circuit is configured to convert a direct current input to the inverter device into an alternating current.
