STEVAL-ILH007V1: 150W HID digital ballast based on STLUX385A
Introduction
This document describes 150 W high intensity discharge (HID) digital ballasts driven by
STLUX385A devices. This platform is a solution to drive HID lamps (sodium and metal
halide). The board is composed of two stages:
1.
Power factor corrector (PFC), based on boost topology to correct the AC input current
in phase with AC voltage mains.
2.
Inverter, based on full bridge topology to drive the lamps.
The STLUX385A digital controller drives both stages.
