This paper proposes a simultaneous controlled dual output full-bridge converter for LED lighting systems. Two LED lamps are powered using a full-bridge. The devices in full-bridge converter are switched at zero voltage using LC resonant circuit. Therefore, switching transition power losses are minimized which increases the LED driver efficiency. An inductor is connected in series with each LED lamp to reduce ripple current. Thus, the use of electrolytic capacitor can be eliminated. This feature increases lifespan of proposed resonant LED driver. Symmetrical Voltage Cancellation control is designed for both regulation and dimming operation. Numerical simulations are carried out to validate the performance of the proposed LED converter circuit configuration.
