The invention relates to an electromagnetic shielding device and an inverter, the electromagnetic shielding device comprises a wave-shaped bending structure, a fixing structure arranged on the bending structure and a bending rib structure arranged at one end of the bending structure, and the shielding device is fixed on an inverter shell through a screw. The inverter upper cover and the inverter shell are respectively provided with a wave-shaped groove with a section similar to that of the shielding structure, so that the upper part and the lower part of the shielding device can be respectively clamped into the wave-shaped grooves. And the bent rib structure at the upper part of the shielding device is in interference fit with the clamping groove structure of the inverter upper cover. Compared with the prior art, the device has the advantages of high structural reliability, convenience in application, cost saving and the like.
