Industrial Full Bridge

For power levels above 100-150 watts, the state-of-the-art topology is based on a boost converter (power factor controller, or PFC) working in fixed off time or in transition mode and an inverter composed of a full bridge that drives the lamp with a low-frequency square wave. This limits the lamp current during the warm-up phase and controls the lamp power during the run phase. ST's innovative design and technologies, combined with system know-how, are supported with dedicated demonstration boards. The kits allow customers to perform a comprehensive evaluation of the product, and then to use the base hardware/software design as a starting point for their own project development.
