摘要
对锂电池车载充电机的输出纹波噪声进行了分析，设计了差模噪声和共模噪声抑制电路，对两级LC滤波电路和共模噪声抑制电路的参数进行了计算。样机实验结果表明，车载充电机输出纹波达到了技术要求，电磁干扰小。
Output ripple and noise of lithium battery on-borad charger was analyzed,differential mode noise and common-mode noise suppression circuit was designed,parameters of the bipolar LC filter circuit and the common-mode noise suppression circuit was calculated. Prototype experimental results show that output ripple of the on-borad charger meet the technical requirements and electromagnetic interference is weak.
