Introduction to PMIC - PFC (Power Factor Correction)

Power Factor Correction (PFC) is an electronic power management technique of controlling a power system’s power factor in order to provide efficient power utilization. The Power Factor Correction (PFC) technique is employed to ensure that the electrical system’s consumption of active power is equal to the actual power consumption. PFC improves the line current harmonic content, makes the voltage distortion smaller, reduces system losses from reactive power, and enhances power quality.

L6563A Application Field and Working Principle

The L6563A is an integrated power factor correction (PFC) controller designed for use in high-power AC/DC converter applications. It features a single-ended current-mode control topology to regulate the input current for both continuous conduction mode (CCM) and discontinuous conduction mode (DCM) operations. The chip offers an integrated 180° boost diode, a high-voltage gate driver, and soft-start circuitry. It is compatible with various low-frequency and high-frequency resonant topologies. The operating principle of the L6563A PFC controller is based on the phase control control logic. When the current loop is in control, the phase control angle is determined by a fixed phase advance angle (α). The IC adjusts the input current to balance the power factor while the spread cycle modulator senses the output voltage, adjusts the turn-on angles of the drains, and controls the output power. The L6563A PFC controller is most suitable for high-power industrial and lighting applications. The high output power range and wide input voltage range make it suitable for applications with large power loads. The L6563A PFC controller also has a wide temperature range and can adapt to different operating temperatures.

Conclusion

The L6563A is an integrated power factor correction (PFC) controller designed for large-scale AC/DC converter applications. It features a single-ended current-mode control topology to regulate the input current for both continuous and discontinuous conduction modes. The L6563A PFC controller is most suitable for high-power industrial and lighting applications due to its wide output power range and wide input voltage range, as well as its wide temperature range that allows it to work in different operating temperatures.
