Title: BI-DIRECTIONAL CONVERSION APPARATUS
Abstract:
A bi-directional conversion apparatus, comprising a current sampling apparatus and a transformer. The current sampling apparatus is used for collecting current information of a first side of the transformer. The transformer is used for converting energy of an input side of the bi-directional conversion apparatus to an output side by means of transformer isolation. The bi-directional conversion apparatus may control and protect a bi-directional circuit, lower apparatus design costs, and reduce apparatus volume.
