The ballast is composed of a boost converter (power factor controller PFC) working in transition mode and an inverter consisting of a full bridge that drives the lamp at low-frequency square wave. s b O The ballast was developed for 185 - 265 Vac 50/ 60 Hz input mains and is able to drive 150 W metal halide and high-pressure sodium lamps.
