- AC DC Desktop, Wall Adapters: PSA05A-050QW Application Field and Working Principle
- Introduction
- PSA05A-050QW is a high-efficiency, high-reliability AC/DC desktop and wall adapter. It is a 31 watt, single-output, AC/DC adapter with industry standard dimensions that incorporates active power factor correction (PFC), offering superior performance over traditional AC/DC adapters.
- Application Fields
- PSA05A-050QW AC/DC desktop and wall adapters can be used in consumer electronics, medical and industrial applications. It is also suitable for powering laptop computer systems, notebook computers, PC/Peripheral/LAN hardware, VoIP telephone, and other electronic appliances and system.
- Working Principle
- The AC/DC adapter employs active power factor correction (PFC) technology, which enables the adapter to achieve high efficiency and power factor. It is designed using a synchronous rectification conversion topology to achieve a low total harmonic distortion (THD). The adapter also complies with the original EN50413 and UL60950 directives and bears the UL and CE marks.
- The Power Factor Correction(PFC) circuit of PSW05A-050QW consists of an inductor, a diode, a power transistor and a control circuit. The control circuit monitors the voltage at the output of the rectifier and on the filter capacitors. When the output voltage begins to drop, the control circuit sends a signal to the power transistor to switch on, thus allowing current to flow to the output via the inductor. As the current passes through the inductor, the voltage across it increases, thus creating a positive feedback cycle to increase the output voltage. After the output voltage has increased, the control circuit sends a signal to the power transistor to switch off, thus disconnecting the current flow. This is how the PFC circuit maintains a constant output voltage.
- Conclusion
- PSA05A-050QW is an ideal production for powering laptop computer systems, notebook computers, PC/Peripheral/LAN hardware, VoIP telephone, and other electronic appliances and system. It employs active power factor correction technology and offers superior performance over traditional AC/DC adapters with low total harmonic distortion.
