Working Principle of FNP300-1012G

The primary circuit of the FNP300-1012G AC-DC converter consists of an input PFC circuit and a full-bridge. The input rectifier bridge converts the input AC voltage to DC voltage, and the integrated DC/DC controller regulates the current flow in the primary side of the converter.On the secondary side, the converter uses a full-bridge inverter stage to rectify the input DC voltage and convert it to an output voltage. The output voltage is then regulated by an integrated current-mode controller, which is able to provide precise control loop compensation, thus ensuring that the output voltage variations remain under control.The controller also regulates the switching frequency, and thus reduces audible noise. Furthermore, the controller handles the over-voltage and the over-current feedbacks, so that the output voltage is always maintained within an acceptable range. Finally, the controller also includes an integrated voltage loop compensation, which allows for better stability when the system is not running at full load.

Conclusion

In conclusion, the FNP300-1012G AC-DC converter is a high efficiency, low noise, and stable AC-DC converter that can be used in a variety of light industrial, industrial, leisure, medical, automotive, and many other applications. Its sophisticated design and integrated features make it an ideal solution for a variety of applications. It offers superior transient response and an integrated protection circuit for extra safety.
