Abstract
An emergency converter according to the invention is used in lighting applications for operation from an energy storage device in case of mains failure. The converter device comprises a charger circuit configured to charge the energy storage device and a microcontroller circuit configured to control the charger circuit. The driver circuit is preferably implemented in a coupled inductor boost circuit topology. The microcontroller circuit is further configured to control the switch based on a zero crossing of a measured inductor current.
