This document describes the performance, technical data and the connection of the SSL2109 reference board. The SSL2109 is an NXP Semiconductors controller IC intended to provide a low cost, small form factor LED driver. The reference board is intended to operate at 230 V or 120 V (AC), using an output voltage of 30 V or greater.

The board is optimized for a 230 V (50 Hz) or 120 V (50 Hz or 60 Hz) mains supply. In addition to the mains voltage optimization, the board is designed to work with multiple LEDs or an LED module with a high forward voltage. Mains connection of the reference
board is different from other general evaluation/reference boards. Connect the mains to the screw connector J6.

The SSL2109 is a highly in共模电感tegrated switching mode LED controller which enables Constant Current (CC) driving from the mains input. It is a sol共模电感器ution for small to medium LED retrofit lamp application, especially for low-power factor design. The SSL2109 is a 铁芯电感器buck converter controller suitable for non-isolated, non-dimmable LED retrofit lamps. It can drive long LED strings with, typically 70 V forward voltages. The SSL2109 is intended to operate wi贴片电感th higher output voltages, as in modern LED modules.

问一个变压器的问题我们的变压器,经检验,同名端和异名端可以确定,
但是接到电路中,初级线圈的两个线头按下图的方法接入时,
次级根本没电压输出.

如果把初级线圈的两个线头反过来接的话,就可

自适应PID控制在试验电源组中的应用 摘 要： 将神经元自适应的控制模型与常规PID控制算法相结合，设计了一种自适应PID控制器，并将其应用于风力发电机试验系统电源组的控制系统中。该控制器不仅结构简单、参数易于整定，且具有较好的自适
