A converter is a device that transforms the information emitted by the source according to a certain purpose. The matrix converter is a new type of AC-AC power converter. Compared with traditional converters, it has the following advantages: no need for an intermediate DC energy storage link; capable of four-quadrant operation; having excellent input current waveform and output voltage waveform; and freely controllable power factor. The matrix converter has become one of the hotspots in power electronics technology research and has broad application prospects.
