能馈式的LED阵列接口电路
摘要：
一种能馈式的LED阵列接口电路由n个通道电路以及1个具有调光功能的多通道电流控制器组成。通道电路j（j=1，...，n）由输入电容Cij、电感Lj、N-MOS管Mj、二极管Dj、电容Caj、耦合电感Laj和Lbj、N-MOS管Maj、二极管Daj、输出电容Coj构成。与通道电路j匹配，具有调光功能的多通道电流控制器拥有端口vc、端口vs、端口vgj、端口vsj、端口vgaj、端口vsenj、端口vpj。本实用新型通过自身的调节作用来解决LED阵列中各支路的不一致性问题，同时通过自身的多余能量收集及回馈作用来实现高效率的LED阵列驱动，适用于任意LED阵列（规则或不规则）的驱动系统。
摘要（英）：

An energy-feedback LED array interface circuit is formed by n channel circuits and one multi-channel current controller having a dimming function. Each channel circuit j (j=1,...,n) is composed of an input capacitor Cij, an inductor Lj, an N-MOS pipe Mj, a diode Dj, a capacitor Caj, coupled inductors Laj and Lbj, an N-MOS pipe Maj, a diode Daj and an output capacitor Coj. The multi-channel current controller matched with the channel circuits j and having the dimming function is provided with a port vc, a port vs, a port vgj, a port vsj, a port vgaj, a port vsenj and a port vpj. The energy-feedback LED array interface circuit solves the problem that various branch circuits in an LED array are not inconsistent through a regulation effect of the LED array interface circuit, meanwhile, efficient LED array drive is achieved through collection and feedback effects of excess energy of the LED array interface circuit, and the energy-feedback LED array interface circuit is suitable for drive systems of random regular or irregular LED arrays.
