摘要： The present invention is related to a switched-mode power supply. It is also related to a LED lighting system and driver which comprise such a switched-mode power supply. In addition, the present invention is related to a method for electrically driving a load. According to the present invention, the switched-mode power supply is switched from a charging state, in which an energy storage is charged, to a discharging state, in which the energy storage feeds a load, when a current limit has been exceeded. This current limit is set proportional to an instantaneous voltage outputted by the rectifier.
