UC3854 High Power Factor Preregulator

UC3854 High Power Factor Preregulator

UC3854 Preregulator for active power factor correction with low noise sensitivity and fixed-frequency PWM.

The UC3854 High Power Factor Preregulator enhances power efficiency by correcting power factor in systems that draw non-sinusoidal current. This device offers essential control functions, including a voltage amplifier and a current amplifier, to minimize line-current distortion. It operates effectively within a voltage range of 75 to 275 volts and supports both single and three-phase systems.

With features like average current-mode control, the UC3854 ensures stable operation while maintaining a sinusoidal line current. Its low start-up supply current and high reference voltage reduce noise sensitivity, making it suitable for various applications. The fixed-frequency PWM drive allows for chopping frequencies exceeding 200kHz, ensuring optimal performance.

Applications of the UC3854 High Power Factor Preregulator include efficient power supply designs in industrial and commercial settings. This device is crucial for minimizing distortion and improving overall power quality, making it a reliable choice for Indian electronics customers.
