    • An apparatus, method and system are disclosed for supplying power to a load such as a plurality of light emitting diodes. An exemplary apparatus comprises a primary module (515), a first secondary module (520 1 ) couplable to a first load (130 1 ) , and a second secondary module (520 2 ) couplable to a second load (130 2 ). The primary module (515) comprises a transformer having a transformer primary. The first secondary module comprises a first transformer secondary magnetically coupled to the transformer primary, and the second secondary module comprises a second transformer secondary magnetically coupled to the transformer primary, with the second secondary module couplable in series through the first or second load to the first secondary module. When energized by a power source (110), the first secondary module (520 1 ) has a first voltage polarity and is couplable in a series with the first load (130 1 ) configured to have an opposing, second voltage polarity, which substantially offset each other to provide a comparatively low resultant voltage level.
    • 公开了一种用于向诸如多个发光二极管的负载供电的装置,方法和系统。 示例性装置包括主模块(515),可耦合到第一负载(130 1)的第一辅助模块(520 1)和可耦合到第二负载(130 2)的第二辅助模块(520 2)。 主模块(515)包括具有变压器初级的变压器。 第一次级模块包括磁耦合到变压器初级的第一变压器,并且第二次级模块包括磁耦合到变压器初级的第二变压器次级,其中第二次级模块通过第一或第二负载串联连接到第一变压器 二级模块。 当由电源(110)激励时,第一次级模块(520 1)具有第一电压极性,并且可与第一负载(130 1)串联耦合,该第一负载被配置为具有相对的第二电压极性,其基本上抵消 彼此提供相对较低的合成电压电平。
