The application of supercapacitors in power electronic devices, such as inverters and rectifiers.

They can smooth current, reduce harmonics, improve system efficiency, extend equipment life, and also provide instantaneous power compensation and stable voltage.

It has a wide range of applications in wind power generation systems, photovoltaic power generation systems, motor drive control, and other fields. They can significantly improve the performance and reliability of the system, reduce electrical equipment failures, and thus extend its service life.
