Application Notes
- U-134 UC3854 Controlled Power Factor Correction Circuit DesignPDF, 346 Kb, File published: Sep 5, 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 - AC Requirements for Power Factor Correction CircuitsPDF, 29 Kb, File published: Mar 28, 2002
This technical brief identifies the recommended range of IAC for each of the devices within the UCC3854 family of PFC controllers. - DN-39E Optimizing Performance in UC3854 Power Factor Correction ApplicationsPDF, 277 Kb, File published: Sep 5, 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 - Accurate PWM Duty Cycle ClampPDF, 58 Kb, File published: Jan 25, 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. - DN-41 Extend Current Transformer RangePDF, 37 Kb, File published: Sep 5, 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.
