Abstract:
1. An inverter comprising: a noise reducing coil; a smoothing capacitor; an inverter module that includes P-N terminals in which DC power is input, a power system board and a control board; and a terminal block to which power cables from a power source are connected and to which DC power supplied from the power source is input, wherein the power system board converts the DC power which has been input to the P-N terminals to AC power and supplies the AC power to an electric motor; the control board controls the AC power to be applied to the electric motor; the smoothing capacitor is electrically connected, on the inverter module, in parallel with the power system board; the noise reducing coil includes at least two coils, that is, a common mode coil and a normal mode coil; input lead wires of the common mode coil are directly connected to the terminal block; output lead wires of the common mode coil are directly connected to the terminal block and the P-N terminals; an input lead wire of the normal mode coil is directly connected to the terminal block; and an output lead wire of the normal mode coil is directly connected to the P-N terminals wherein the normal mode coil is provided, downstream of the common mode coil, at each of the P-pole side and the N-pole side.
