Introduction to 98-1062TRPBF Power Factor Correction (PFC)

Power factor correction (PFC) or power factor regulation is the process of adjusting the input current of a power supply to better match the output voltage, to increase overall power efficiency. Power factor correction is increasingly important as the demand for high-performance power supplies increases, as it can help identify and correct issues with power supply performance from the source.

The 98-1062TRPBF is a two-stage, AC/DC integrated PFC converter that provides high power density and high efficiency for power supplies used in medium to high applications. This integrated solution includes an input PFC stage and an output stage, and improves the power factor performance by reducing power loss. The 98-1062TRPBF is designed to save additional space and reduce cost and maintenance time by providing an integrated, fully-optimized solution.

Application Field of 98-1062TRPBF

The 98-1062TRPBF is an integrated two-stage AC/DC PFC solution. It can be used in applications such as desktops, servers, printers, copiers, industrial equipment and other general-purpose electronic systems. It provides high power density and high efficiency for power supplies used in medium to high-end applications.

Its wide input voltage range of 90VAC to 265VAC makes it suitable for a variety of power input sources. It is also designed to meet international standards for power factor and has a lower total harmonic distortion (THD) rating. Additionally, the 98-1062TRPBF has a standby power reduction feature that can reduce power consumption to meet government regulations and improve efficiency.

Working Principle of 98-1062TRPBF

The 98-1062TRPBF uses a two-stage topology that combines an input PFC stage with a synchronous rectifier output stage. This two-stage architecture reduces power losses and improves the efficiency of the power supply.

In the input PFC stage, the controller operates in discontinuous conduction mode (DCM) and sets the current at a level appropriate to achieve power factor correction. The output stage operates in continuous conduction mode (CCM) and synchronizes the boost rectifier. Its wide input voltage range allows the controller to switch between CCM and DCM as needed. This two-stage PFC converter also uses primary-side sensing, which eliminates the need for additional optocouplers, further reducing its cost and size.

The output stage has two channels for filtering the output current ripple and providing a stable DC output voltage. The controller can also be programmed to limit the peak current, protecting the converter and providing increased safety.

Conclusion

The 98-1062TRPBF is a two-stage AC/DC integrated PFC converter designed to meet efficiency standards while providing high power density and high efficiency. It can be used in a variety of applications as it has a wide input voltage range and can be programmed to limit the peak current. Its two-stage topology combines an input PFC stage and a synchronous rectifier output stage, reducing power loss and providing a stable output voltage.
