Abstract :
A simple design method for a class-D series-parallel (LCC) resonant inverter suitable for electronic ballast applications is proposed. Variations in the power delivered to the lamp, caused by the lamp aging, are limited to fulfil the standards. This design results in cost-effective circuits, as its functionality is aimed at simplifying the power stage.
