Switching power supply system for optical sources or a load requiring a controlled supply current
Abstract:
A switching power supply for supplying a load requiring a controlled current includes a PFC pre-regulator for receiving an input voltage and providing an output voltage, and a DC-DC switching converter for receiving at input the voltage output by the pre-regulator and for providing at output a supply voltage of said load. The switching DC-DC converter operates at a fixed and constant operating frequency, is a resonant converter and includes an LLC resonant circuit.
Abstract(Chinese):

用于提供需要受控电流的负载的开关电源包括用于接收输入电压并提供输出电压的PFC预调节器，以及DC-DC开关转换器，用于在输入端接收预调节器输出的电压， 在输出端提供所述负载的电源电压。 开关DC-DC转换器工作在固定和恒定的工作频率，是谐振转换器，并且包括一个LLC谐振电路。
