The advantage of high-power LED lighting of new double string LLC structure can be summed up in the following four: The first is the rise efficiency,the new topology structure actual overall efficiency can reach 92%. The second is the cost is low, because it does not need to each string DC/DC buck, a string of transformer TI can drive the two string of LED, two string of transformer can drive the four string of LED, all adopt the traditional transformer, and the cost far less than a constant voltage DC/DC to drive each string. Third,it have very little components, so the reliability is very good, the constant voltage and constant current the whole integrated in a module, rather than two, make the reliability rise. In addition, at present the traditional scheme use much more capacitances, because each string DC/DC need capacitance, PFC also need capacitance LLC also is capacitance. Capacitance damage is also an important factor that influence the reliability of the street lamp LED . The framework of capacitance number is less, no LLC, DC/DC capacitor, so reliability rise. Fourth, EMI problem decreases, and design is more simple. The circuit have no string together DC/DC, it only need a resonant half bridge make drive, so that you can easily get EMI design.After the board design complete, can basically through the conduction testing, due to the characteristics of the circuit LLC is very good EMI, a very performance circuit, for traditional topological structure,EMI is very good. In addition, the circuit can be compatible with dimming,it still can cooperate with TI Zigbee wireless adjust light, because IC is on the side or simulate light, LED light, adjust the whole string LED light and realizing whole PWM or analog dimmer. |
