Description

The STEVAL-ILH004V1 demonstration board

implements a digital ballast for a 70 W HID lamp

(sodium or metal halide) used in general lighting

applications. The ballast is composed of a boost

converter (power factor controller PFC) working in

transition mode and an inverter composed of a

half-bridge that drive the lamp in low-frequency

square wave.

Both the half-bridge and the PFC stage are

managed by the ST7LITE49K2 that controls the

L6382D5, activating all the power switches.
