Working Principle

XL10PP010DC is a high-frequency switch-mode power supply, which has the advantages of small size and high efficiency. The working principle is similar to that of other switch-mode power supplies, but it uses a high-frequency MOSFET low-voltage switch tube to improve its performance. It consists of 3 major sections: the power factor improved unit, the PWM rectifier unit and the power output section.

Power Factor Improved Unit

The power factor improved unit of the XL10PP010DC power supply includes an input rectifier filter and an active power factor corrector. The rectifier filter converts the AC mains to a DC voltage of 355V. The active power factor corrector (APFC) can correct the input power factor of the power supply, and supply a stable input voltage to the PWM rectifier unit.

PWM Rectifier Unit

XL10PP010DC has an AC/DC voltage infrared bridge for its PWM rectifier unit. The bridge is made up of four power MOSFETs. When the PWM signal is received, one of the two power MOSFETs in the bridge will be switched on, charging one of the capacitors on the DC voltage side of the power supply, and the other capacitor will be discharged in a controlled way. When the PWM signal is off, the other two power MOSFETs will turn on, this time charging the other capacitor on the DC voltage side of the power supply, and the other capacitor will be discharged in a controlled way. This process will be repeated, and the end effect is that the voltage on the DC voltage side of the power supply will remain constant.

Power Output Section

The power output section includes a DC/DC converter and an output filter. The DC/DC converter uses pulse width modulation (PWM) signals to adjust the output voltage of the power supply. The output filter is used to reduce the voltage ripple and improve the power output quality of the power supply.

Conclusion

XL10PP010DC is a high-frequency switch-mode power supply, which has the advantages of small size and high efficiency. It is widely used in power supply for medical ultrasound and medical electronic instruments, communication power, industrial, household appliances, entertainment industry and other industries. Its power factor improved unit, the PWM rectifier unit and the power output section work together to ensure the stability of the power supply output, making the power supply more reliable.
