Abstract
With the rapid development of power electronics technology, power electronic devices are playing an increasingly important role in energy conversion, smart grid construction and other fields. Through the efficient and accurate power conversion and control, these devices greatly improve the efficiency of energy utilization, and promote the intelligent development of the power system. This paper focuses on the electromagnetic compatibility of power electronic devices, and first summarizes the basic principle of electromagnetic compatibility, the basis of power electronic technology, and the theory of electromagnetic field and electromagnetic wave. This paper analyzes the important role of power electronic devices in improving energy conversion efficiency and the development of smart grid. On this basis, the electromagnetic compatibility problems include harmonic interference, conduction interference, radiation interference and electromagnetic sensitivity problems. This paper proposes a series of effective countermeasures to solve these problems. In harmonic control, active filter technology and optimized power electronic device design are adopted to reduce harmonic generation; in the conduction interference suppression, apply EMI filter and reasonable layout and wiring to reduce conduction path; in the aspect of radiation interference control, strengthen shielding design and optimize antenna effect management; and in the countermeasures to improve electromagnetic sensitivity, strengthen circuit protection and isolation and adopt electromagnetic compatibility design software.
