access icon free Soft switched full-bridge light emitting diode driver configuration for street lighting application

This study presents a light emitting diode driver circuit topology based on a full-bridge configuration with dimming control. It is more suitable for high power lighting loads. The proposed configuration has advantages of zero-voltage switching, reduced component count and high efficiency. It can power multiple lighting loads. Operation of the proposed circuit configuration is explained in detail and it is validated through simulated and experimental results on the 145 W experimental prototype with dimming control.
