Abstract

Provided is an inverter, comprising a conversion module, a delivering module, an inductance module, and a communication module. The delivering module and the inductance module are separately connected to the conversion module by means of plug-in, and the communication module is electrically connected to the delivering module, the conversion module, or the inductance module by means of plug-in. The electrical connection between the modules inside the inverter can be realized by means of plug-in, such that the electrical connection between the modules is more convenient, the working efficiency and maintenance efficiency of electrical connection are improved, and the influence of the electromagnetic interference, which is occurred when the modules are connected by means of wires, on the working stability of the modules can be avoided, thereby ensuring the working stability of the inverter.
