Abstract
Provided in the present application is a micro inverter. In a main circuit of the micro inverter, after N conversion branches are cascaded with each other, the same transformer is shared to connect a secondary-side bridge arm, thereby avoiding the need for N transformers in the prior art; moreover, by means of cascading, the N conversion branches can realize decoupling in terms of control, thereby avoiding the need to additionally equip each branch with a device for decoupling, and thus reducing the volume and costs. In addition, each direct-current source or load can realize alternating-current grid connection only by means of one-stage conversion, and therefore, the conversion efficiency is improved compared with a two-stage conversion structure in the prior art.
