In addition, the FPS100048/PS features a low-noise operation with a maximum noise level of under 50mV peak-to-peak.

Working Principle:

The FPS100048/PS AC-DC converter operates by taking an alternating input voltage of 90 to 290V and converting it into a regulated and constant DC output voltage of 5 to 700V. The AC-DC converter uses a three-stage boost topology to provide the necessary output voltages. The converter is composed of the input rectification, the voltage boost stage, the PFC stage, as well as the output filter.

The first stage of the AC-DC converter is the input rectification which consists of a full bridge rectifier and capacitor bank. The rectified signal is then fed to the boost stage, where the signal is amplified and filtered with an inductor and capacitor. This signal is then taken and fed into the PFC stage. The PFC stage is composed of two DC-DC converters in a single-switch topology. This stage compensates for any power loss and also helps reduce ripple. The last stage of the AC-DC converter is the output filter which consists of an inductor, capacitor and diode. The filter is used to ensure the clean and smooth output and also to reduce line harmonics.

Conclusion:

The FPS100048/PS AC-DC converter provides high efficiency and superior performance along with excellent power factor correction to reduce cost and emissions. Its wide range of inputs and outputs make it suitable for various applications. The efficient boost circuit also helps reduce the size and cost of the system. The output filters help ensure a clean and stable DC signal as well as reduce line harmonic distortion.
