【应用】黑金刚铝电解电容EKXG451ELL820MMP1S在工业级嵌入式AC-DC电源模块应用
工业级嵌入式AC-DC电源模块专用电源的产品应用：
项目参数：
输入交流电源：110-240V/50Hz
输出直流电压：两组双路输出+24V/10A、一组隔离输出+12V /8A
PFC电压和电流： 400V/0.5A (200W)
输出功率：200W
输出电压纹波 ：小于100mV
项目原型设计之初，开关变压器有鸣音(啸叫)，人耳朵可以听到声音20HZ-20kHz范围, 除了交流输入电流的噪声峰峰值纹波抑制会引起变压器振荡，还有以下原因会导致变压器产生高频或者低频鸣音
● 变压器的生产装配工艺问题、变压器的磁芯和气隙的长度不适合。
● 纹波电压太高，不稳定
● 滤波电容 容量不足
● 纹波峰值应小于额定输出电压，
为了保证PFC控制电路电压情况下能够有足够的控制范围内不产生振铃音频噪声，经过相位补偿调整计算再配合微调变压器匝数。故选型品质可靠长寿命黑金刚82u F/450V 工业级高压滤波电容。整流滤波电容必须有平滑直流电压输出，解决变压器有鸣音异常问题。
