Abstract

The invention provides a bidirectional isolation digital converter which comprises a primary side digital controller, a secondary side digital controller, an isolation circuit, an isolation transformer, an input voltage sampling circuit, an output voltage sampling circuit, a bidirectional current sampling circuit, an input power driving circuit, an output power driving circuit, a primary side driving circuit and a secondary side driving circuit. According to the embodiment of the invention, the primary side digital controller and the secondary side digital controller are adopted, and the isolation circuit and the isolation transformer are arranged between the primary side digital controller and the secondary side digital controller so that power output from input to output can be realized,and power output from output to input can also be realized; in addition, by arranging the isolation device, the converter can be applied to high-power occasions or occasions where sparks are prone tobeing generated, and the requirements of users are met.

Description

technical field [0001] The present application relates to the technical field of power electronic products, and more specifically, relates to a bidirectional isolated digital converter. Background technique [0002] With the development of microgrid technology and energy storage technology, the research on bidirectional converter technology has received extensive attention. Bidirectional converters can be used for bidirectional conversion of AC voltage and DC voltage, and energy can be realized at the input and output ends of the converter. two-way flow. [0003] Most of the existing bidirectional converters do not have an isolating device. Such bidirectional converters are not suitable for high-power or occasions where sparks are likely to be generated, and cannot meet the needs of users. Contents of the invention [0004] The present application provides a bidirectional isolation digital converter, which can be applied to occasions with high power or where sparks are li...
