Description

technical field [0001] The invention relates to the technical field of power electronics, and more specifically, relates to a digital multifunctional teaching experiment platform for power electronics technology. Background technique [0002] Power electronics technology is a new electronic technology applied in the power field, which is the technology of using power electronic devices (such as thyristors, GTOs, IGBTs, etc.) to convert and control electric energy. The "electricity" power transformed by power electronics technology can be as large as hundreds of MW or even GW, or as small as several W or even less than 1W. Unlike information electronics technology that focuses on information processing, power electronics technology is mainly used for power conversion. Power electronics technology has become an indispensable professional basic course for modern electrical engineering and automation majors, and plays an important role in cultivating talents for this specialty. ...
