STEVAL-ILB009V1 2 x 28 W electronic ballast with active PFC based on the STD3N62K3 and STD845DN40 BJT devices
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.
