| Popis: | This paper presents a family of insulated drivers to feed LED lamps to street lighting system. Aiming increase the lifetime of the LED driver, this work presents a PI controller to reduce the capacitance value and replace the electrolytic capacitor by another technology of capacitor with longer lifetime. Four isolated converters topologies are presented and analyzed. Experimental results are presented for all proposed topologies. All of them present high power factor, low THD and comply with the IEC 61000-3-2 standard. |
