LED lighting hot trend pull up drive power supply market.

The development trend of high efficiency, small volume and green environment will make new demands on electronic transformer and inductance.
The development trend of power supply is more and more efficient, and the volume is smaller and smaller, and it is also required to meet the requirements of green environment. LED drive power supply more no exception, high efficiency, small volume, green environmental protection become the trend of the development of the LED drive power supply, no doubt, also the application of electronic transformer and inductor put forward higher requirements.
Zhao Yi told reporters: "we need to improve the efficiency of conversion of LED drive power supply, mainly from two aspects, the first is the choice of raw materials, magnetic components in terms of inductance, choose a little coarse inductance, such a high amount of magnetic induction, loss is relatively small; Second, we should start from the solution, using the soft switch technology, provide good working conditions for such components makes devices under zero voltage or zero current conditions state transition, so as to reduce the device switch loss to a minimum." In short, the loss of components should be reduced to the lowest level to improve the power conversion efficiency. Liu guoliang also pointed out: "the high efficiency of the power supply requires the components to be relatively small in the performance of the switching loss, otherwise it will affect the efficiency of the power supply."
Temperature rise conditions are factors influencing the power efficiency is extremely important, especially for high power LED street light, to improve the power conversion efficiency, must pay attention to the rise of temperature of the power operation problem, there is no doubt that application of components also face more challenges. Zhao Yi pointed out: "for outdoor lighting of the LED drive power supply, need under the condition of high temperature operation, the scope of work required - 35 ℃ ~ + 60 ℃ even wider, so temperature scope is also put forward higher requirements for components."
