150 W HID digital ballast based on the STLUX385A
  • Preview Preview

The STEVAL-ILH007V1 product evaluation board is a 150 W high intensity discharge (HID) digital ballast platform for testing the STLUX385A digital controller.

This solution is designed to drive sodium and metal halide HID lamps. The board is composed of two stages, the power factor corrector (PFC) and the inverter.

The PFC is based on a boost topology to correct the AC input current in phase with the AC voltage mains. The inverter is based on a full bridge topology to drive the lamps. The STLUX385A digital controller drives both stages.

The STLUX385A is part of the ST’s MASTERLUX™ family of digital devices tailored to lighting and power conversion applications.

The MCU has a 16 MHZ CPU frequency, 32 Kbytes of program memory and 2 Kbytes of RAM.

The firmware is available as an Intel HEX file.
