Power Factor Correction (PFC) is the process of correcting the power factor of a circuit to improve system efficiency. Power factor correction is used most commonly in applications where high voltage AC power is used, such as industrial and commercial applications. One of the most commonly used PFC controllers is the UCC28512DWR. This PFC controller is a microcontroller-based power factor correction controller with an output voltage peak current mode control. This PFC controller also has many features such as power-backup mode, current sharing control, cable drop protection, over-voltage protection, over-current protection, and over-temperature protection.

The UCC28512DWR is a high performance power factor correction (PFC) controller for use in an isolated half-bridge power supply design. The device includes an embedded 8-bit microcontroller, a current-mode PWM controller with 16-bit current sense resolution, a power backup mode, current sharing control and support for multiple fault monitoring and protection functions.

The UCC28512DWR power factor correction controller works by controlling the power supplied to the load by actively regulating the input voltage in real time. It monitors the input voltage and current, adjusting the output voltage accordingly. This helps to reduce harmonic distortion, ensuring that the output waveform is of optimal quality. The controller also helps to minimize energy losses, improving the overall efficiency of the power supply design.

The controller is implemented in a single stage topology, which is ideal for computing, consumer, and industrial applications where space is limited and a low cost solution is preferred. It also features a low external component count, making it easier to implement in existing applications. Additionally, its power backup mode allows the system to sustain a reduced power factor in the event of a sudden power loss, ensuring that the supply remains stable.

By using the UCC28512DWR, designers can ensure that the power factor of a power supply design is consistently maintained at optimal levels. This increases system efficiency and reduces energy losses, saving money on energy costs and helping to extend the system’s life. Additionally, by utilizing the controller’s various fault monitoring and protection functions, designers can ensure that their design is safe and reliable.
