U-134 UC3854 Controlled Power Factor Correction Circuit Design
PDF, 346 Кб, Файл опубликован: 5 сен 1999
The UC1854 provides active power factor correction for power systems that otherwise would draw non-sinusoidal current from sinusoidal power lines. This device implements all the control functions necessary to build a power supply capable of optimally using available power-line current while minimizing line-current distortion. This application note describes the concepts and design of a boost prere

DN-39E Optimizing Performance in UC3854 Power Factor Correction Applications
PDF, 277 Кб, Файл опубликован: 5 сен 1999
The performance of the UC3854 Power-Factor Correction IC in the 250W application example has been evaluated using a precision PFC/THD instrument. The result was a power factor of 0.999 and Total Harmonic Distortion (THD) of 3.81%, measured to the 50th line frequency harmonic at nominal line and full load. Users should get similar results at these conditions. as well as over most line and load rang

DN-41 Extend Current Transformer Range
PDF, 37 Кб, Файл опубликован: 5 сен 1999
The problems with self reset of current transformers for unipolar pulse applications can be overcome with simple forced-reset techniques derived from magnetic amplifiers. Duty factors above 90% are achievable with these techniques. This design note describes a circuit configured for forced reset and a configuration that generates a negative voltage from the current transformer.

Accurate PWM Duty Cycle Clamp
PDF, 58 Кб, Файл опубликован: 25 янв 2002
Power supply applications using current sense transformers require a duty cycle clamp on the pulse width modulator (PWM) to ensure transformer reset. Not all PWMs come with a duty cycle clamp presenting a problem for the power supply designer. This application note shows how to implement a duty cycle clamp by using a simple delay circuit.
