STEVAL-ILH007V1 150 W HID digital ballast based on the
STLUX385A
Introduction
This document describes the digital ballast for 150 W High Intensity Discharge (HID), driven
by the STLUX385A device. This platform is a complete solution for driving HID lamps. The
STEVAL-ILH007V1 is also designed to receive commands from the PLM remote control
unit, to create a network for street lighting based on power line communication. The board
consists of two stages:
1. A Power Factor Corrector (PFC) based on boost topology to correct the AC input
current in phase with AC voltage mains.
2. An inverter based on full bridge topology to drive the lamps.
Both stages are driven by the STLUX385A digital controller.
The PFC and output stage have been analyzed in all phases, and some design criteria with
test results are given.
