Abstract

Disclosed herein is an inverter. The inverter includes 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.

Claims

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.

2. The inverter according to claim 1, wherein 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.

3. The inverter according to claim 2, wherein 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.

4. The inverter according to claim 1, wherein the main board is grounded by contacting a metal rod connected to the heat dissipation part, the metal rod penetrating the main board.

5. The inverter according to claim 4, wherein the control board is provided with a ground connection part,

wherein a ground screw is installed at the ground connection part, the ground screw contacting the heat dissipation part.

6. The inverter according to claim 5, wherein the control board is electrically connected to an I/O board disposed on the main board, the control board fixing the I/O board,

wherein the I/O board is provided with a pattern connected to the ground connection part.
