Abstract

The invention provides a power conversion integrated system for scientific research and teaching. The power conversion integrated system comprises a power network, a miniature energy router and a switching device, wherein the power network is used for supplying an alternating current to the miniature energy router, the miniature energy router is used for generating different types of electric energy, and the switching device is used for changing flow directions of the electric energy; and at least two modes of providing electric energy are achieved by converting the electric energy of an alternating source to different types of electric energy and / or changing the flow directions of the electric energy. The miniature energy router of the power conversion integrated system is an integrated body of power conversion equipment resources and can generate different types of electric energy, and the switching device distributes the electric energy, thus the power conversion equipment resourcesare subjected to secondary integration indirectly, therefore, at least two modes of providing electric energy can be achieved, electric energy is provided to different loads, an integrated power conversion system is formed, the power conversion equipment resources are saved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of electric power experiment equipment, in particular to a comprehensive power conversion system for scientific research and teaching. Background technique [0002] With the development of power electronics technology and the expanding field of power electronics applications, research on different combination applications of power electronic converters is becoming more and more popular, such as two-terminal / multi-terminal DC transmission systems, doubly-fed wind power generation back-to-back converter systems, For DC microgrid systems, battery charge and discharge management systems, power quality processing systems, etc., the traditional electronic topology is discrete, and its control and application range are very limited. Researchers in different fields or topics often need to conduct experiments on various power systems, which requires building multiple different power systems. These power systems are very large ...
