roduc ^Description
P The STEVAL-ILB001V2 demonstration board is a
te ^{complete reference system for a simple cost-}
effective PFC (power factor corrector) using
le _{bipolar transistors and is intended for low-to-}
so ^{medium power HF ballasts.}
b _{The proposed bipolar PFC solution targets the}
O _{low-cost HF ballast market up to 80 W as it}
- _{provides a simple cost-effective solution without}
t(s) ^{sacrificing THD and PF levels. No additional ICs}
are required for the PWM signal as the device
c _{uses just a power bipolar transistor and a closed-}
u _{loop feedback which performs the duty cycle}
rod ^{modulation and output power regulation.}
P The active PFC solution with bipolar transistor
te ^{adopts the boost topology operating in}
Obsole ^{discontinuous-conduction mode.}
