Description
The STEVAL-ILB009V1 demonstration board is
able to drive a 2 x 28 W electronic lamp ballast
with active PFC. The ballast is formed by a PFC
section and a self-oscillating half bridge converter.
The circuit has been designed for a nominal input
voltage of 230 Vrms ± 15% and 50-60 Hz.
The key components are the power bipolar
transistor (STD845DN40), MOSFET device
(STD3N62K3) and ST power switching driver for
the PFC section.
The purpose of the STEVAL-ILB009V1 is to show
a simple and cheap lighting application optimized
in terms of power factor (PFC), THD harmonic
distortion, and electrical efficiency.
