The converter converts the information sent by the source for a certain purpose. The matrix converter is a new type of AC-AC power converter. Compared with the traditional converter, it has the following advantages: no intermediate DC energy storage link; four-quadrant operation; excellent input current waveform and output voltage waveform; freely controllable power factor. Matrix converter has become one of the hotspots in power electronics technology research and has broad application prospects.
The circuit is suitable for the frequency range of the alarm. XTAL is a value-based quartz crystal, T1 and C1 are tuned to the input frequency. The simple short-wave converter used in the AM radio is an example of the application of the circuit. As shown in the figure, it can also be used. Pass the frequency adjustable oscillator.
