1. An inverter comprising:
- a base provided with a heat dissipation part;
a main board disposed on the base to output an input power along an independent power flow through a rectification part and a inverter part; and
a control board fixed to be electrically connected to the main board to form a flow of a secondary power and a flow of an electrical signal, the flow of the secondary power and the flow of the electrical signal being independent from each other,wherein the main board comprises an input power connection part to receive the input power, the rectification part, a DC link, an inverter part, and an output terminal, andwherein an area of the main board is wider than an area for installation of the heat dissipation part,wherein the independent power flow is formed through the input power connection part, the rectification part, the DC link, the inverter part, and the output terminal, andwherein the main board further comprises an SMPS power connection part,wherein the control board is fixed to a side portion of the main board, the control board comprising;
an SMPS power input unit electrically connected to the SMPS power connection part to input the secondary power, a controller, an SMPS power unit, and a signal unit,wherein the SMPS power unit generates the secondary power and forms the flow of the second power transmitted to the controller and the signal unit,wherein a signal flow is formed between the controller and the signal unit.
