AC DC Converters: PR60 Application Field and Working Principle

An AC-DC converter, also known as an AC-DC power adapter, is a device that converts alternating current (AC), which is most commonly generated by the electrical power grid, into direct current (DC). This conversion is useful when DC power is needed to operate a device that would typically run on AC alone. The PR60 by Beijing-Limar is a high performance AC-DC converter designed specifically for applications that require an ultra-high input voltage and a highly efficient conversion rate. Specifically, the PR60 is used in applications like LED lighting, automotive, HVAC and UPS systems.

Features of the PR60

• Ultra-Compact (73x48x31mm)
• Highly efficient conversion rate of over 95%
• 40~1200V AC input voltage range
• Overcurrent protection
• Isolation voltage of 50kVac
• Reverse polarity protection
• High reliability

The Working Principle of the PR60

The PR60 incorporates a series of electronic components in order to achieve its high efficiency rating. It begins with a rectifier bridge connected to the AC input voltage. The rectifier bridge is a device that converts AC to DC power while allowing for the easy adjustment of the output voltage using a variable resistor. This rectified DC output is then inverted to produce an AC voltage, which is used in the power factor correction circuit. This circuit corrects the AC input voltage waveform to achieve a higher power efficiency. Finally, the corrected AC is fed into a buck converter, which converts it into a DC voltage. The buck converter is the primary component responsible for the PR60\'s ultra-high efficiency rating.

Applications

The PR60 is designed to work in a variety of applications, most notably in LED lighting, automotive, HVAC and UPS systems. The PR60 can handle input voltages ranging from 40 to 1200V AC, and features a high efficiency power factor correction circuit for improved performance. Its compact size and high efficiency make it an ideal choice for applications where power must be delivered reliably, quickly, and with a high degree of efficiency.

Conclusion

The PR60 by Beijing-Limar is a high performance AC-DC converter designed for applications that require an ultra-high input voltage and a highly efficient conversion rate. Its rectifier bridge, power factor correction circuit, and buck converter all contribute to its high efficiency and wide range of supported input voltages. The PR60 is used in applications like LED lighting, automotive, HVAC and UPS systems.
