Switched-mode power supply, LED lighting system and driver comprising the same, and method for electrically driving a load
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.
摘要（中）：

本发明涉及开关电源。 它还涉及包括这种开关模式电源的LED照明系统和驱动器。 另外，本发明涉及一种电驱动负载的方法。 根据本发明，当已经超过了电流限制时，开关模式电源从其​​中蓄能器充电的充电状态切换到能量存储器馈送负载的放电状态。 该电流限制与整流器输出的瞬时电压成比例。
