Bipolar power diodes

electronic ballast
Understanding PFC - Lighting applications
What is Power Factor Correction (PFC)
Ñ
It can be defined as the reduction of the harmonic content,
and/or the aligning of the phase angle of incoming current
Ñ
PFC is required to reduce disturbance on the AC distribution
net and maximize the real power drawn by the power supply
from the AC line.

PFC benefits
Ñ
Fully compliant with regional regulations imposing
restrictions on power factor and total harmonic
distortion (THD) in high-power applications (>75W),
including:
- CCC or ‘3’C in China
- IEC1000-3-2/EN61000-3-2 in Europe
- ‘80plus policy’ in America
- JICC61000-3-2 in Japan
Ñ
Meets energy saving and ‘green energy’ trends
to reduce electricity costs
Ñ
Optimizes and improves circuit performance
- reduces mains harmonic content
- decreases peak current at mains frequency
- minimizes the electrolytic bulk capacitor used
at PFC stage output
- shrinks mains transformer size and weight
- improves output regulation of downstream
