Power Factor Correction (PFC) is an important component of power management that is used to improve the power efficiency of AC power systems. UCC28063AD is a PFC controller that is designed to optimize designs driven by Power Factor Correction circuits. It can be used in a variety of applications and is ideal for applications requiring high accuracy, low cost and light weight. Its wide input voltage range supports both standard and low voltage loads, making it a versatile solution for a wide range of projects.

The UCC28063AD controller is a high-performance analog IC that can provide complete three-phase active power factor correction from single-phase AC power sources. It can handle up to two times the average current, allowing it to achieve a high output power efficiency. The controller has two modes of operation – single-phase and three-phase – and both of these modes use peak current-mode control, which makes it suitable for both low and high frequency switching applications.

The UCC28063AD has a wide input voltage range, which means it can be used in applications with a wide range of input voltages. This makes it suitable for both commercial and industrial applications, as well as applications where the input voltage changes, such as solar and wind power systems. The device also has high power density and high power efficiency, which makes it well-suited for applications that require high power outputs. It can handle over-temperature conditions, making it ideal for high ambient temperature applications, such as in automotive applications.

The UCC28063AD controller works by actively controlling the input power factor of AC sources. This is done by continuously measuring the current drawn from the AC source and comparing it to a programmed setpoint. This comparison is then used to adjust the current drawn by the load to bring it into line with the required setpoint and ensure a power factor close to one. This helps ensure that the current drawn from the AC source is only used to power the load, not to dissipate in the form of reactive power.

The controller is designed to be used in both constant voltage and constant current applications. It also has AGC (automatic gain control) and PWM (pulse width modulation) modes of operation to adjust the output voltage and current as required. The AGC mode is useful for regulating the output of constant voltage power supplies and the PWM mode is useful for controlling the output of constant current power supplies. The device also has over-voltage and under-voltage protection built in, helping to ensure safety in applications that require a reliable power supply.

The UCC28063AD can also be used to control multiple loads simultaneously, as it can provide simultaneous three-phase output control. This makes it suitable for high power applications, such as electric vehicle charging applications. The device can be used to support high efficiency, low component count designs, as it is designed to maximize power efficiency while minimizing component count.

The UCC28063AD is an excellent choice for a number of applications that require efficient power factor correction. Its wide input voltage range and its ability to control multiple loads ensures it is a versatile solution for a wide range of projects. Its high power density and power efficiency make it a suitable solution for high power applications, such as electric vehicle charging applications. With its over-voltage and under-voltage protection, the UCC28063AD ensures safety and reliability in a variety of applications.
